Unable to post confirmation for the PO

Hi,

Unable to post confirmation for the PO in SRM 7.0 .

Error messages:

Line 1: Error in account assignment for line 1.

Line 1: Auxiliary account assignment not possible.

It looks like line item does not have the cost center attached to it any more. It had the cost center attached when SC was created and the PO was issued. Now however, it does not have the cost center attached, and receipt cannot be posted for this line item.

Please respond.

Regards,

Niru
