Dear Raymond,
Thanks for your reply.
As i have posted my code in IF_EX_ME_PROCESS_PO_CUST~PROCESS_ACCOUNT only but its working fine whenever a new line item is created.
But whenever am trying to change the same line the method IF_EX_ME_PROCESS_PO_CUST~PROCESS_ACCOUNT is not getting triggered, where i can set the value of cost center.
But the method IF_EX_ME_PROCESS_PO_CUST~PROCESS_ITEM is triggering whenever am changing the line item.
Kindly suggest me how to change the cost center value whenever am changing the line item.
Thanks
Vijayan R.
