Problem with updating net price value through PORDCH Idoc

Hi All,

I have a ABAP program which calls the function module BAPI_PO_CHANGE to update the line item details using an idoc.

During this change it is updating Limit values in PO bot not the net price.

And the Idoc status is having message as BAPI Change has been done successfully instead of "PO number changed".

Any suggestions to solve this issue.

Thanks,

Spandana
