SAP Note 27881 - Cost center in GR/IR clearing line

Symptom:

Question: For an invoice receipt in the GR/IR clearing item, why is the CO account assignment object (for example, the cost center or the order) set, and why is the consumption account additionally stored in the BSEG-SAKNR field?

Cause and prerequisites
Solution
Up to and including Release 2.2, this information is needed for purchase order processing with valuated goods receipt, in order to create a document with reference to the CO invoice, particularly if the invoiced amount corresponds to the amount from the purchase order and, therefore, no posting is made to the invoice receipt consumption account. The information in CO about the CO account assignment object and the usage cost element is taken from the GR/IR clearing item and a line item is created for this account assignment object and the usage cost element with value and quantity set at zero. This document is used to validate the expense account for external services during auditing.
As of Release 3.0, this validation is carried out differently, for the purchase order number is now written in the CO line item. This enables you to determine all expense accounts for an external service by calling up the purchase order history.
