BAPI_PO_CREATE1 and BAPI_TRANSACTION_COMMIT

HI gurus,

Currently I have an RFC call from PI to SAP FM BAPI_PO_CREATE1, but tables are not updated in SAP.

when I run the bapi in ECC6 I need to run the following BAPIs in sequence to make it work:

1) BAPI_PO_CREATE1

2)BAPI_TRANSACTION_COMMIT

now, my question is, if RFC is calling from PI, then, do I also need to call the BAPI_TRANSACTION_COMMIT in sequence from PI?

I found the note 187687 that mentions that it is required the commit with the BAPI_PO_CREATE, but not sure about BAPI_PO_CREATE1

Do you know the answer to it?

thanks so much

Ivan
