Map Database Output to an EDI 810 Invoice

Overview

CData Arc contains powerful tools to retrieve targeted data from back-end databases and map this data into an outbound EDI document (X12, EDIFACT, etc). This guide walks through the process of creating a database-to-EDI workflow, focusing on generating an X12 810 document (invoice). The sample invoice mirrors the syntax required by Amazon.

The approach and principles described in this article are also applicable to generating other EDI documents; however, there might be differences in the specific data pulled from the database and the relationships between mapped values.

This guide begins with an overview of how to accomplish the mapping in Arc, then walks through each step of the mapping flow. See Sample Data to review the database structure, output files, and the resulting 810 document used in this article.

EDI Mapping in CData Arc

Pulling Database Data as XML

Arc uses XML as a common format for data transformation and manipulation. All EDI mapping flows involve converting the source data (in this case database data) and destination data (in this case an EDI file) into XML.

All Arc connectors that pull data from databases (or database-like applications) automatically format the output data as XML files. Thus, data that is pulled from a database is immediately ready to be mapped or transformed. This guide uses the Database connector configured with a MySQL driver to interface with a MySQL database.

Pulling Data Relevant for an 810 Invoice

Invoices are typically sent to trading partners in response to a purchase order (PO). When a manufacturing company receives a PO that requests a set of manufactured goods, the manufacturing company responds with an invoice to pay for the requested goods.

As a result, the data used to generate an invoice typically comes from a PO received earlier. This guide assumes that incoming PO data is automatically inserted into a database, so the PO database tables hold the data relevant to the 810 invoice. When you configure a Database connector for this mapping flow, the Database connector targets the tables where the PO data is held.

POs can contain multiple line items, and a typical database setup stores line item data in a LineItems table that is separate from the PurchaseOrders table. The LineItems table has a foreign key to the PurchaseOrders table in order to know which line items are associated with which PO, but data must be pulled from both tables in order to retrieve all of the necessary information to populate an 810 invoice.

The section in this guide dedicated to configuring a Database connector includes the steps necessary to pull from both a PurchaseOrders table and a LineItems table (with the appropriate foreign key relationship) at the same time.

Representing an EDI Document as XML

In order to map the XML data pulled from a database into an EDI document, the EDI document must also be represented as XML. Arc includes many different connectors to convert between EDI and XML formats (X12 and EDIFACT are two). This guide focuses on mapping an X12 document, so the X12 connector is used to generate an XML representation of the target 810 document.

It is important to have a sample output document (such as a sample 810) prior to creating the mapping flow. This sample document is used to create the XML model for the mapping step.

Transforming XML Structures

Once the source and destination formats have been represented as XML, the powerful XML Map connector is used to transform one XML structure into the other.

The XML Map connector requires a sample Source File and Destination File, which represent the starting and ending XML structures respectively. The XML output pulled from the database is the source file, and the XML representation of an X12 810 document (generated by passing a sample 810 through an X12 connector) is the destination file.

Once you specify the source and destination structures, the XML Map connector’s visual designer is populated with the two structures. Drag and drop elements from the source structure onto elements in the destination structure to create a mapping relationship between them. This mapping step requires an understanding of the EDI structure so that the appropriate elements are included in the output file.

The XML Map connector includes value formatters, conditional logic, and even custom scripting to manipulate and compute data during the mapping process.

Once you create the mapping relationship, the XML Map connector can automatically convert any files that match the source XML structure into a file with the destination XML structure. In this example, this means that the data pulled from a database is automatically converted into an XML model of an X12 810 document. The final step is to take the XML model of an 810 CSV file and convert it to an actual 810 document, which is easily accomplished with the X12 connector.

Creating the Mapping Flow

This section contains each step to create a flow in Arc that retrieves database output and maps it to an 810 invoice.

Step 1: The Database Connector

The first step of a mapping flow is to configure a Database connector to pull the relevant data from a MySQL back-end.

Establishing a Connection

Click the Flows tab, then add an instance of the Database connector to a workspace canvas (see Designing a Flow for instructions). For production flows, the Database connector instance name should include the target database (in this case MySQL) and context information about the data being pulled or pushed into the database (for example, MySQL_Invoice_tradingPartner). In this flow the connector instance name is Database for simplicity.

The Database connector is a general connector that can interface with many different types of databases, so it must be configured with the appropriate database driver to target a specific database. Arc includes a MySQL driver as part of the application, so no additional steps are required to install the MySQL driver where the Database connector can read it.

After you select the MySQL driver, the Database connector Settings tab automatically populates with the connection settings required for the target database. Enter the connection properties (or connection string) required to connect to the MySQL database.

Click Test Connection to verify that the connector can successfully establish a connection to the target database.

Creating the Output Mapping

Once a connection is established, create an output mapping to pull the relevant data from the database. As mentioned in Pulling Data Relevant for an 810 Invoice, the output mapping must pull from a parent PurchaseOrders table and a child LineItems table.

On the Database connector Settings tab, set Action to Select. Click Add to create a new output mapping. This brings up a list of tables in the database. Select the parent table (with PO data). You will add the child table (with line item data) later. In this example the PO table is test_purchase_orders, and selecting this table launches the Mapping Editor:

Use the editor to select which columns in the table to retrieve; this guide includes all of the columns in the output XML.

One of the table columns is Processed, which holds the value 0 if a record has not been processed, and 1 if it has. When POs are inserted into the table, it is expected that the Processed column is set to 0. The output mapping should only pull records if the Processed column is 0, and it should update this column with the 1 after successfully pulling a record.

To accomplish this, apply a filter to only pull records where Processed = 0. In the Filter section of the editor, add a new rule:

Set the left dropdown to the column to check—Processed in our example
Choose the logical operator in the middle dropdown—Equals in our example
Set the right input to the value to compare against the column—0 in our example

In addition to filtering records by the Processed column, the column needs to be updated so that records are not pulled more than once. The Advanced section of the editor allows you to specify a column that should be updated when rows are successfully pulled from the database.

In this case, the Processed column should be updated with the value 1:

Now that the appropriate records will be pulled from the test_purchase_orders table, the output mapping must be configured to pull the line items associated with each PO. In this example, the line item data is held in the test_po_line_items table.

In the mapping editor, click Add to add a new table to the mapping. Select the test_po_line_items table:

The editor automatically updates with the table tree structure in the left panel. As with the test_purchase_orders table, you can select specific columns from the test_po_line_items for output; this guide includes all of the columns.

When the Database connector pulls a PO record from the test_purchase_orders table, it also looks to pull records from the test_po_line_items table. Only line items associated with the current PO should be pulled, so a WHERE constraint must be applied on the child table.

In this example, the PONumber column in the test_po_line_items table corresponds to a PONumber column in the test_purchase_orders table. Records should only be included in the output for a PO record when the PONumber from a line item matches the PONumber from a PO.

To accomplish this, add a new rule to the Filter section of the test_po_line_items mapping:

Set the left dropdown to the column in the child table to check—PONumber in our example
Set the middle dropdown to Equals
Set the right input to reference the parent table by clicking the dropdown arrow and selecting REF (the $ symbol appears to indicate a reference)
Set the last input to the column in the parent table to compare—PONumber again in our example

The output mapping is now fully configured, and can be saved in the Database connector.

Once this mapping has been saved, you can pull data from the database in two ways. If Receive Automation is enabled on the Automation tab of the Database connector, the connector automatically attempts to pull un-processed POs (and the associated line items) according to the Receive Interval. Alternatively, you can manually pull records navigating to the Output tab and clicking Receive.

Output Mappings as XML

After an output mapping is created, the Database connector represents the mapping as XML. To view the XML model of the mapping, click the </> button to the right of the mapping:

When the Database connector pulls data from the database, it uses the retrieved values to populate an XML document with this structure. Sub-structures in the XML file can repeat; for example, if multiple line items are pulled for a single PO, the XML sub-section for the test_po_line_items table repeats for each line item.

This XML structure needs to be mapped to an XML structure representing an X12 810 invoice. Then the resulting mapped XML can be converted directly to an EDI document.

Note: The mapping used for this guide is in Database Output Mapping.

Step 2: The X12 Connector

The X12 connector performs two roles in this mapping flow.

It is used to generate an XML representation of a sample 810 invoice. This XML sample is used later, in the XML Map connector, to map the database output into an EDI structure.
The X12 connector performs the last step in the flow when it converts the XML generated by the XML Map connector into an X12 document.

Add an instance of the X12 connector to the canvas. X12 connector instance names should typically include the name of the trading partner sending X12 documents. In this flow the instance name is X12_Outbound for simplicity:

Upload a Test File

The Upload Test File feature simplifies the process of generating an XML model for the target EDI document. Open the X12 connector Input tab and click More > Upload Test File:

Browse to a sample 810 invoice to upload. The X12 connector generates an XML model of this document internally, which the XML Map connector can automatically detect. Since the model is stored internally, the external appearance and configuration of the connector does not change.

Note: The sample 810 document used for this guide is in X12 810.

Configuring the X12 Connector

In addition to creating a sample XML model, the X12 connector is used to convert XML mapped by the XML Map connector into the output EDI file. In addition to converting the XML format into X12 format, the X12 connector adds interchange and functional group data to the document according to the settings configured in the connector. Thus, it is important to configure the X12 connector with the settings specific to the partner who will receive the outbound X12 810 document.

On the X12 connector Settings tab, set the Translation Type property to XML-to-X12. When operating in this mode, input to the X12 connector should be XML that is structured as an EDI document. Using the Create Test File option from the previous step in the XML Map connector ensures that the input XML matches this specific structure.

The connector also fills in interchange and functional group values according to the configured settings. At a minimum, set these values:

Sender Identifier: For outgoing EDI documents this is your identifier (if this value requires qualification, set Sender Id Qualifier to the qualifying value)
Receiver Identifier: For outgoing EDI documents this is your trading partner’s identifier (if this value requires qualification, set Receiver Id Qualifier to the qualifying value)
Test Indicator: Indicates whether an outgoing EDI document should be treated as production or test data.

Your trading partner might require further interchange (ISA) and functional group (GS) values to successfully receive the 810; communicate clearly with your trading partner to find out what header elements are required. See the X12 connector documentation for more information.

Step 3: The XML Map Connector

Now that the Database connector and X12 connector have generated an XML model of the input and output data respectively, use the XML Map connector to transform one XML structure into the other.

Add the XML Map connector to the flow, then connect the Database connector to the XML Map connector and the XML Map connector to the X12 connector.

Configuring the XML Map Connector

On the XML Map connector Settings tab, find the Source File and Destination File fields. The XML Map connector detects the XML model from the Database connector output mapping as an available Source File, and the XML model from the X12 connector test file as an available Destination File. If either option is not available, verify that the test file and output mapping were appropriately saved and that the connectors are connected on the canvas.

Once you specify the Source File and Destination File, the XML Map visual designer automatically populates with the XML structures of the output mapping and the sample X12 810 file.

If the Interchange and FunctionalGroup elements in the Destination structure have Meta elements, you can safely delete them. The X12 connector applies the relevant metadata to the ISA and GS segments when converting the XML to EDI.

Understanding the XML Structures

Creating the right mapping relationships in the XML Map connector requires understanding how the source and destination structures are represented in XML.

First, there are two types of XML elements (nodes) in the structures. Parent nodes are nodes with children but no value. Leaf nodes are nodes with values but no children. A parent node can be expanded to show its children or contracted to hide its children with the + or - signs next to it.

In the Database XML, each parent node represents a table from which data is being pulled, and each leaf node represents a column in that table. In the 810 XML, each EDI loop and segment is a parent node, and each individual EDI element is a leaf node.

Creating the Mapping

Once you configure the XML Map connector with the Source and Destination structures, create the mapping by dragging and dropping nodes in the designer.

Mappings are created in two primary steps:

Creating the Foreach looping relationships between parent nodes
Mapping values between leaf nodes in the established Foreach loops

Creating Foreach Loops

Foreach relationships mean that each time an element appears in the source, a new XML structure should be created in the destination. If ElementA in the source is mapped to ElementB in the destination, each occurrence of ElementA in an input file results in an instance of ElementB (and all of ElementB’s children) in the output file.

In this case, each record pulled from the PO table (PurchaseOrders) results in a new transaction (TX) in the resulting EDI, and each record pulled from the line items table (test_po_line_items) results in a new IT1Loop. Drag the test_purchase_orders element onto the TX-00401-810 element, and the test_po_line_items onto the IT1Loop1 element:

Foreach Loops

Note: The sample X12 810 document used to create the Destination structure might have multiple IT1Loop1 elements that show up in the mapping designer. You can delete all but one of these elements (right-click the node and select Delete Node) because the Foreach relationship ensures that the correct number of IT1Loop1 elements are generated.

Mapping Leaf Nodes

After you establish the Foreach relationships, you can map the values from leaf nodes in the loops. Mapping leaf nodes determines the values that populate the XML structures created by Foreach loops.

Some leaf node mappings are simple, and others require use of the Expression Editor or Script Editor. The following sections cover each of the common types of leaf node mappings in an EDI document. More general information about various mapping features can be found in the XML Map documentation.

Simple Leaf Node Mappings

When a value from the source should be directly inserted in the resulting output, simply drag a leaf node from the source onto a leaf node in the destination to map the values. This process requires an understanding of the EDI destination format and which values need to be included in the resulting X12 document.

For example, the BIG04 element in the X12 810 holds the PO number for which the invoice is created. This corresponds to the PONumber element from the database output. Drag the PONumber node onto the BIG/BIG04 node to establish this relationship:

Mapping Leaf Nodes

The green xpath to the right of a mapped destination node is indicates the source of the mapped value (PONumber in the previous image). Leaf node xpaths are relative to the Foreach xpaths in parent nodes (/Items/test_purchase_orders). The xpath from all parent nodes can be concatenated with the xpath in a leaf node to find the full xpath in the source XML for the mapped value: /Items/test_purchase_orders/PONumber.

In this example, other direct leaf node mapping values include the following:

PODate > BIG/BIG03
CurrencyCode > CUR/CUR02
ItemID > IT1Loop1/IT1/IT107
Quantity > IT1Loop1/IT1/IT102
PricePerUnit > IT1Loop1/IT1/IT104
PONumber (again) > IT1Loop1/IT1/IT111

You can drag and drop each of the source values onto the destination EDI document without modification or conditional logic.

Contextual Mappings

Some leaf node mappings depend on other elements in the destination. For example, an N1Loop1 loop in the destination XML is a collection of elements that represent a party/entity in the EDI transaction (such as billing party, shipping party, purchasing party, and so on). The N1Loop1/N1/N101 element indicates the specific role of the party, and the role of the party determines which values should be mapped from the source XML.

In this guide, the source data includes party details for the ship-to party and the remit-to party. To include this data in the EDI output, you need two separate N1Loop1 structures, one with N1Loop1/N1/N101 set to ST (the value for ShipTo) and one with N1Loop1/N1/N101 set to RI (the value for RemitTo). Then, the N1Loop1/N1/N102 value for each respective loop can be mapped by dragging and dropping ShipToID and RemitToID from the source:

Mapping More Leaf Nodes

Map the other ship-to data (ShipToAddr, ShipToZip, etc) to the N2, N3, and N4 elements in the N1Loop1 structure where N101 is set to ST. Similarly, map the other remit-to data (RemitToAddr, RemitToZip, etc) to the appropriate elements in the N1Loop1 structure where N101 is set to RI.

Note: Some EDI loops require multiple distinct nodes in the Destination mapping (like the N1Loop1 loop in this section), and others require only a single node in the destination mapping (like the IT1Loop1 loop from the previous section). The difference depends on whether a Foreach relationship will automatically generate the correct number of output nodes: since the N1Loop1 node does not have a Foreach relationship associated with it, the destination mapping needs to explicitly include the correct number of N1Loop1 nodes.

Simple Calculations

Some values are not pulled directly from the source XML, but are calculated using one or more of the values in the source. For example, each IT1Loop1 loop (each line item) has a TXI/TXI02 element that represents the amount of tax applicable for that line item. The source data includes all of the information necessary to calculate the tax applied to the purchase:

Price per unit
Quantity
Tax percent

However, the calculated tax value is not itself present in the source, so it must be calculated in the XML Map connector.

The Expression Editor has Formatters that you can use to manipulate data during a mapping. In this case, the multiply formatter is you need to convert the source data into the destination value.

Begin by mapping the PricePerUnit source node onto the IT1Loop1/TXI/TXI02 destination node. This is a good starting point for generating the appropriate mathematical expression because the price per-unit is one of the input valuables in the expression. Then, click the tablet and pencil icon to the right of the destination node to open the Expression Editor:

Expression Editor

Multiply the price parameter with the quantity to find the total cost of the line item; pass the PricePerUnit value to the multiply formatter using the vertical pipe character (|), then set the parameter of the multiply formatter to the value from the Quantity source element:

Multiply Formatter

Note: The xpath value for Quantity must be surrounded by square brackets to be interpreted as a dynamic value instead of a string literal.

This total cost value must be multiplied by the TaxPercent, and by .01 to convert from percent to dollars:

Full Expression

Save the expression and the mapping automatically calculates the appropriate value from the dynamic inputs specified.

Cumulative Calculations

The output 810 document has a TDS segment that represents the total monetary value of the invoice. Summing the cost of each line item requires a persistent variable that can be updated in each line item loop.

Scripting is required to store values in variables and retrieve these values later in the mapping. In ArcScript, values are stored as attributes, and items are objects that can have multiple attributes. Item attributes are referenced with the following syntax: item_name.attribute_name

The \_map item is a special item that retains attribute values throughout the document mapping. In other words, most attributes (variables) are only preserved for a single node mapping, but attributes of the \_map item persist throughout every node in the mapping.

To sum the cost of each line item, set an attribute of the \_map item in the line item’s Foreach loop (in the IT1Loop1 loop). Since this scripting is not associated with any specific elements in the IT1Loop1 loop, add a dedicated Script element to the destination mapping. This element does not appear in the resulting EDI document, but indicates that scripting logic is being performed for some other use in the mapping.

First, right-click the IT1Loop1 element and select New Code Script to add a new Script element (you can reposition this element by clicking and dragging it):

Script Node

The script needs to calculate the full cost of the line item, which can be found with the following formula:

(PricePerUnit * Quantity) + (PricePerUnit * Quantity * TaxPercent * .01)

Edit the Script element to represent this formula in ArcScript:

<arc:set attr="lineItemCost" value="[xpath(PricePerUnit) | multiply([xpath(Quantity)])]" />
<arc:set attr="lineItemTax" value="[lineItemCost | multiply([xpath(TaxPercent)]) | multiply(.01) | round(2)]" />
<arc:set attr="_map.costSum" value="[_map.costSum | def(0) | add([lineItemCost]) | add([lineItemTax])]" />

After this script executes during each line item loop, the _map.costSum attribute holds the total cost (including tax) for all line items. To reference this value in the TDS/TDS01 element, click the </> icon to the right of the TDS01 element and set the result.text value to the attribute from earlier:

Simple Custom Script

Conditional Mappings

Some nodes require conditional logic to determine whether they should appear in the output, and what value should be set in them. For example, the ITD segment includes data about the terms of the invoice, and this only needs to be included in the output 810 if terms are specified.

You can use the Filter icon next to the ITD element in the destination mapping to apply a condition that determines whether the element (and its children) appears in the output document. Click the icon and add a rule in the condition editor; in this case the PO terms will have a prefix that lets us know whether terms must be specified in the invoice:

Simple Custom Script

Now that the ITD element only appears if special terms are specified, the ITD01 element needs to hold the appropriate code for the terms. In this example, the following values should be used for the associated terms:

02 - Expedited Payment
03 - Delayed Payment
11 - Alternative Payment Profile

The values in the Terms element of the input data cannot be converted into the ITD01 value using formatters, so you need a custom script to determine the ITD01 mapping. Click the tablet and pencil icon to the right of the ITD01 element to open the Script Editor; the following script accomplishes the pattern above:

<arc:set attr="termsCode" value="" />
<arc:set attr="termsInput" value="[xpath(Terms)]" />

<arc:select value="[termsInput]">
 <arc:case value="Expedited Payment">
  <arc:set attr="termsCode" value="02" />
 </arc:case>
 <arc:case value="Delayed Payment">
  <arc:set attr="termsCode" value="03" />
 </arc:case>
 <arc:case value="Alternative Payment Profile">
  <arc:set attr="termsCode" value="11" />
 </arc:case>
</arc:select>

<arc:set attr='result.text'>[termsCode]</arc:set>

The above example uses the arc:select keyword, but you can achieve the same result with a series of arc:if and arc:else statements. See the arc:if for more information.

Index Mappings

Some elements in the Destination XML need to count the number of loops in a Foreach relationship. For example, the IT1Loop1/IT1/IT101 element holds the line item number, so it needs to increment for each line item in the PO. Similarly, the Meta/ST02 element needs to increment for each PO in the document.

The \_index attribute is a special variable that holds the index of the most local Foreach loop relationship (for nested Foreach loops, \_index refers to the innermost loop). As long as the Foreach relationships are established correctly, you can set both Meta/ST02 and IT1Loop1/IT1/IT101 to the following value to correctly count the number of POs and line items:

[_index]

This special attribute is also available in any custom scripting environment, if the current index in a Foreach loop is relevant for more advanced mapping logic.

Generating a Date in the Mapping

Some elements in the destination XML do not reference the source data at all. The BIG/BIG01 element represents the date of the invoice, which is not available until the current mapping step.

You can use the special now Date Formatter to generate a new date value for the current datetime. Like all formatters, this is available in the Expression Editor for any node mapping.

All formatters require an input attribute to format. Often, during an XML mapping, the input attribute is a value retrieved with the xpath formatter (in other words, a value parsed from the source XML). In this case, it does not matter what attribute is passed to the now formatter, since it always returns the current datetime. As a result, you can pass the default _ item as a placeholder:

Now Formatter

Note that the parameter passed to the now formatter defines the output format of the date.

Counting Line Items and Total Cost

The CTT segment includes elements for counting the total number of line items and a hash value that represents the total cost of the items. The approach to calculating these values is similar to that which is described in Cumulative Calculations.

The relevant values must be calculated in the section of the mapping where line item data is available (the IT1Loop1 section), and then referenced later in the CTT mapping. This requires a custom script that stores the values in the special \_map item.

In the IT1Loop1 loop (which is mapped with a Foreach relationship to the test_po_line_items records), right click and select New Code Script to add a new Script node. This script is executed each time the mapping loops; in other words, it executes once for each line item. To calculate the values, the number of lines and total cost need to be summed and then stored in an attribute of the \_map item.

The line item count is calculated with a simple counter, and the cost can be calculated with the same formula used in Cumulative Calculations.

<arc:set attr="_map.lineItemCount" value= "[_map.lineItemCount | def(0) | add(1)]">

<arc:set attr="currentCost" value="[xpath(PricePerUnit) | multiply([xpath(Quantity)])]" />
<arc:set attr="currentTax" value="[currentCost | multiply([xpath(TaxPercent)]) | multiply(.01) | round(2)]" />

<arc:set attr="_map.totalCost" value="[_map.totalCost | def(0) | add([lineItemCost]) | add([lineItemTax])]" />

The CTT01 element can map directly to the _map.lineItemCount. Open the Script Editor and simply reference the attribute from earlier:

<arc:set attr="result.text">[_map.lineItemCount]</arc:set>

The CTT02 element can map to the _map.totalCost. However, the CTT hash requires ignoring the decimal point, which is equivalent here to multiplying the cost by 100:

<arc:set attr="result.text">[_map.lineItemCount | multiply(100)]</arc:set>

Flow Summary

The Database connector generates XML from PO data in a back-end system, and this XML is mapped to an EDI format by the XML Map connector. The EDI XML is then passed to the X12 connector to add interchange headers and convert the XML into X12 format.

The most involved step of this flow is the creation of the XML mapping. Mapping requires establishing the Foreach relationships between parent nodes, then mapping individual leaf nodes with a combination of dragging-and-dropping, using the Expression Editor, adding conditionals, and writing custom scripts.
