VDA Connector

Version 23.4.8839


VDA Connector


VDA connectors support generating VDA documents from XML and converting VDA documents into XML.

Overview

When receiving VDA documents, VDA connectors validate interchange headers and convert the VDA document into XML. This is useful as a staging step, because XML is the primary format that CData Arc uses to manipulate data in a flow. The VDA connector automatically reads the input file to determine the appropriate schema, then parses the document according to this schema.

When generating VDA documents, VDA connectors convert XML into VDA document syntax and apply the appropriate interchange headers. This is useful as the final step for creating a VDA document, after the XML data has been fetched and transformed elsewhere in the flow.

Connector Configuration

This section contains all of the configurable connector properties.

Settings Tab

Translation Configuration

Settings related to the core operation of the connector.

  • Connector Id The static, unique identifier for the connector.
  • Connector Type Displays the connector name and a description of what it does.
  • Connector Description An optional field to provide a free-form description of the connector and its role in the flow.
  • Translation Type Whether the connector should convert VDA documents into XML, or generate VDA documents from XML.

Header Settings

Settings related to the VDA interchange headers. When converting documents into XML, the document headers are validated against these settings; when generating documents from XML, these settings are used to generate document headers.

  • Sender Identifier The unique Id identifying the sending party in the VDA communication (when generating a VDA document, this should be your identifier).
  • Receiver Identifier The unique Id identifying the receiving party in the VDA communication (when generating a VDA document, this should be your partner’s identifier).

Automation Tab

Automation Settings

Settings related to the automatic processing of files by the connector.

  • Send A toggle that instructs the connector to automatically send files when they are ready.
  • Resend Interval The interval the connector waits before resending a file that received a negative ACK. For example, if a trading partner receives the file but something is wrong with it and they send back a negative ACK, this setting specifies how long to wait before sending the file again.
  • Max Attempts (async) The maximum number of times the connector processes the input file when a functional ACK is requested. Success is based on the return of a functional ACK within the Resend Interval. If a successful functional ACK is not returned, the connector resends the file until Max Attempts is reached. If this is set to 0, the connector resends the file indefinitely.

Performance

Settings related to the allocation of resources to the connector.

  • Max Workers The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Settings > Automation page.
  • Max Files The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Settings > Automation page.

Alerts Tab

Settings related to configuring alerts and Service Level Agreements (SLAs).

Connector Email Settings

Before you can execute SLAs, you need to set up email alerts for notifications. Clicking Configure Alerts opens a new browser window to the Settings page where you can set up system-wide alerts. See Alerts for more information.

Service Level Agreement (SLA) Settings

SLAs enable you to configure the volume you expect connectors in your flow to send or receive, and to set the time frame in which you expect that volume to be met. CData Arc sends emails to warn the user when an SLA is not met, and marks the SLA as At Risk, which means that if the SLA is not met soon, it will be marked as Violated. This gives the user an opportunity to step in and determine the reasons the SLA is not being met, and to take appropriate actions. If the SLA is still not met at the end of the at-risk time period, the SLA is marked as violated, and the user is notified again.

To define an SLA, click Add Expected Volume Criteria.

  • If your connector has separate send and receive actions, use the radio buttons to specify which direction the SLA pertains to.
  • Set Expect at least to the minimum number of transactions (the volume) you expect to be processed, then use the Every fields to specify the time frame.
  • By default, the SLA is in effect every day. To change that, uncheck Everyday then check the boxes for the days of the week you want.
  • Use And set status to ‘At Risk’ to indicate when the SLA should be marked as at risk.
  • By default, notifications are not sent until an SLA is in violation. To change that, check Send an ‘At Risk’ notification.

The following example shows an SLA configured for a connector that expects to receive 1000 files every day Monday-Friday. An at-risk notification is sent 1 hour before the end of the time period if the 1000 files have not been received.

Advanced Tab

EDI Delimiters

Settings that specify which characters separate elements, segments, and so on.

  • Suffix Appears at the end of segments to distinguish them from each other.

Advanced Settings

Settings not included in the previous categories.

  • Batch Transactions An exchange can contain multiple transactions. When this is not checked, the connector creates a separate output file for each transaction in the exchange. When checked, the connector groups all transactions into a single output file. Only applicable when the Translation Type is VDA to XML.
  • Encoding Specifies the character encoding (such as ASCII or UTF-8).
  • Expand Qualifier Values When checked, XML elements containing a VDA qualifier include child elements containing the qualifier code and value. For example:
    <N101>
     <Code>ST</Code>
     <Value>Ship To</Value>
    </N101>
  • Functional Acks By default, all functional acknowledgments (997, 999) are routed to the connector selected in the flow diagram, and XML translations are not received in the Output tab. Check this to have the translated acknowledgment also be included in the Output tab. This allows functional acknowledgments to be integrated into a destination source in addition to new EDI documents.
  • Generate Description As When translating VDA into XML, descriptions of the VDA segments and elements can be provided as context for the VDA data. Use this dropdown to choose whether to add this context as an XML comment or as XML attributes.
  • Local File Scheme A scheme for assigning filenames to messages that are output by the connector. You can use macros in your filenames dynamically to include information such as identifiers and timestamps. For more information, see Macros.
  • Nest Loops When checked, the connector detects VDA structures that have hierarchical relationships embedded in the VDA data, and generates XML with these hierarchical relationships represented as parent-child relationships.
  • Processing Delay The amount of time (in seconds) by which the processing of files placed in the Input folder is delayed. This is a legacy setting. Best practice is to use a File connector to manage local file systems instead of this setting.
  • Strict Schema Validation Whether the connector should Ignore, Warn, or Fail when the following are detected: repeat counts above the allowed number, missing required elements or segments, invalid qualifier and code values, disallowed element lengths, and invalid element values. Choosing Disable turns off the schema validation checks.

Message

  • Save to Sent Folder Check this to copy files processed by the connector to the Sent folder for the connector.
  • Sent Folder Scheme Instructs the connector to group messages in the Sent folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all messages for the week in that folder. The blank setting tells the connector to save all messages directly in the Sent folder. For connectors that process many messages, using subfolders helps keep messsages organized and improves performance.

Logging

  • Log Level The verbosity of logs generated by the connector. When you request support, set this to Debug.
  • Log Subfolder Scheme Instructs the connector to group files in the Logs folder according to the selected interval. For example, the Weekly option instructs the connector to create a new subfolder each week and store all logs for the week in that folder. The blank setting tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance.
  • Log Messages Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Input or Output tabs.

Miscellaneous

Miscellaneous settings are for specific use cases.

  • Other Settings Enables you to configure hidden connector settings in a semicolon-separated list (for example, setting1=value1;setting2=value2). Normal connector use cases and functionality should not require the use of these settings.

VDA to XML

When generating XML, set the Translation Type to VDA to XML. The connector then processes VDA files placed in the Input tab. The connector validates VDA message headers against the Sender Identifier and Receiver Identifier configured in the Header Settings. After validating the transmission, the VDA segments are converted into XML according to the schema specified in the message. The resulting XML files are placed in the connector’s Output tab.

XML to VDA

When generating VDA files, set the Translation Type to XML to VDA. The connector then processes XML files placed in the Input tab. The connector converts the XML elements representing a VDA file into VDA segments, then uses the Sender Identifier and Receiver Identifier fields configured in the Header Settings to generate the transmission headers. To create an example of the XML structure required to generate VDA documents, start with an example VDA document and send it through the VDA connector in VDA to XML mode. You can use the resulting XML as a template in the XML Map connector to convert XML structures into a VDA structure.

Macros

Using macros in file naming strategies can enhance organizational efficiency and contextual understanding of data. By incorporating macros into filenames, you can dynamically include relevant information such as identifiers, timestamps, and header information, providing valuable context to each file. This helps ensure that filenames reflect details important to your organization.

CData Arc supports these macros, which all use the following syntax: %Macro%.

Macro Description
ConnectorID Evaluates to the ConnectorID of the connector.
Ext Evaluates to the file extension of the file currently being processed by the connector.
Filename Evaluates to the filename (extension included) of the file currently being processed by the connector.
FilenameNoExt Evaluates to the filename (without the extension) of the file currently being processed by the connector.
MessageId Evaluates to the MessageId of the message being output by the connector.
RegexFilename:pattern Applies a RegEx pattern to the filename of the file currently being processed by the connector.
Header:headername Evaluates to the value of a targeted header (headername) on the current message being processed by the connector.
LongDate Evaluates to the current datetime of the system in long-handed format (for example, Wednesday, January 24, 2024).
ShortDate Evaluates to the current datetime of the system in a yyyy-MM-dd format (for example, 2024-01-24).
DateFormat:format Evaluates to the current datetime of the system in the specified format (format). See Sample Date Formats for the available datetime formats
Vault:vaultitem Evaluates to the value of the specified vault item.

Examples

Some macros, such as %Ext% and %ShortDate%, do not require an argument, but others do. All macros that take an argument use the following syntax: %Macro:argument%

Here are some examples of the macros that take an argument:

  • %Header:headername%: Where headername is the name of a header on a message.
  • %Header:mycustomheader% resolves to the value of the mycustomheader header set on the input message.
  • %Header:ponum% resolves to the value of the ponum header set on the input message.
  • %RegexFilename:pattern%: Where pattern is a regex pattern. For example, %RegexFilename:^([\w][A-Za-z]+)% matches and resolves to the first word in the filename and is case insensitive (test_file.xml resolves to test).
  • %Vault:vaultitem%: Where vaultitem is the name of an item in the vault. For example, %Vault:companyname% resolves to the value of the companyname item stored in the vault.
  • %DateFormat:format%: Where format is an accepted date format (see Sample Date Formats for details). For example, %DateFormat:yyyy-MM-dd-HH-mm-ss-fff% resolves to the date and timestamp on the file.

You can also create more sophisticated macros, as shown in the following examples:

  • Combining multiple macros in one filename: %DateFormat:yyyy-MM-dd-HH-mm-ss-fff%%EXT%
  • Including text outside of the macro: MyFile_%DateFormat:yyyy-MM-dd-HH-mm-ss-fff%
  • Including text within the macro: %DateFormat:'DateProcessed-'yyyy-MM-dd_'TimeProcessed-'HH-mm-ss%
