Commit Issue

Hello Experts,

I am trying to update PO in system B based on some change scenario in system A.

I am calling BAPI_PO_CHANGE in system A.

Sometimes PO is not getting changed and also i am not getting any application logs. I tried to simulate in quality, not faced any issue for 5 records.

Am i wrong in commiting?

I am attaching part of the code for your advice.

Thank You in advance!

Best Regards,

LLD
