The Integration ID field is a key field in the BAPI mapplet. Each BAPI/RFC mapplet includes an Integration ID input field and output field.
When you run a mapping with a BAPI/RFC mapplet, the Secure Agent makes a BAPI/RFC call to SAP to process the data. By default, the BAPI/RFC mapplet commits every 1000 rows when you run a mapping.
The BAPI/RFC call is based on the input data of the Integration ID ports. The Secure Agent makes one call to SAP for each Integration ID. Pass a value to the Integration ID ports in the scalar input group and all mandatory table input groups of the BAPI/RFC mapplet.
You must map the Integration ID input field even when a BAPI or RFC does not require other input fields.
If the BAPI/RFC call fails or if there is a data conversion error, SAP passes the data for the integration ID in comma-separated format to an error output group. If the mapping contains a target instance that is connected to the error output group, the Secure Agent writes the data to the target.
