Steps
Execute the BAPI function module (e.g. via an RFC client library) and check its RETURN table for error messages of type E or A before proceeding
Only call BAPI_TRANSACTION_COMMIT after confirming no errors in the RETURN table; passing WAIT = 'X' causes the call to wait for asynchronous update tasks to complete
If errors exist, call BAPI_TRANSACTION_ROLLBACK before exiting to avoid partial commits in the SAP LUW
Handle the RFC communication error (connection drop) separately from a BAPI application error — an RFC exception means the commit call itself did not reach SAP
Log the RETURN messages from BAPI_TRANSACTION_COMMIT itself, as database-level errors can surface here even if the BAPI appeared to succeed
Known gotchas
BAPI_TRANSACTION_COMMIT has an import parameter WAIT; omitting it (leaving it blank) executes a simple COMMIT WORK without waiting for asynchronous updates, which can cause downstream processes to read stale data
Never call COMMIT WORK directly from external RFC clients — BAPIs manage their own LUW and direct COMMIT statements from outside can corrupt the transaction
A successful RFC call to BAPI_TRANSACTION_COMMIT does not guarantee business-level success; always re-read the committed record or check the RETURN table for deferred errors
