A boolean indicating if the odata service supports server side formulas.
OData has a number of server side formulas that are built into the specifications. However, many services do not natively support them and will throw errors when these formulas are appended to the $filter parameter. These formulas can be used to make some queries that use them execute much faster. If your OData service supports formulas, change this connection property to true. Otherwise, leave it as false.
