Hi Ankit ,
I did the same thing. But there is no commit work provided by BAPI_PO_CREATE1 .
So nothing is updated in the database tables NAST, EKKO and EKPO etc unless SRM triggers the BAPI_TRANSACTION_COMMIT from SRM.
So we cant write code in ECC as all the tables will not have PO specific data in tables at the time when BAPI_PO_CREATE1 exists.
Regards,
Sachin
