There have been times when an ABAPer needs to execute multiple function modules/BAPIs for testing purpose, at a time, which is pretty common in the case while executing a BAPI. For example, some BAPIs needs a BAPI_COMMIT to be executed just after the execution of the Main BAPI you want to execute.
To execute multiple BAPIs/ function modules at a time in SE37:
1. When into transaction SE37, goto Function Module->Test->Test Sequence.
2. Following screen will pop-up. Enter Function Modules / BAPIs in sequence and press OK to execute in sequence.
You can also save BAPI/ Function Module sequence and call it again when needed using Get Sequence button on second screen.
