Oracle Applications‐to‐IS transactions perform selects of information that is stored in the Oracle Applications DBMS. It can be selected for viewing, in which case the service can be invoked and no acknowledgment needs to be done.

More often the transaction will be invoked from a flow service that processes the business transaction (such as sending it to another business).

After the transaction is successfully processed, your flow needs to call the acknowledgment service. The acknowledgment service marks the corresponding data (for example a PO, Invoice) as processed, ensuring that the same data will not be returned in subsequent calls to the service.

Within a flow, you can map values to a service’s queryParams input record, and to the dataRecord input record for the service’s associated acknowledgment service.
