Requires Assignment Co Object Sap

Dear All,

We have prepay for equipment and trying to run these prepaid through the project. We need to post into this prepaid GL account.

We are unable to create an account assignment to PO to the Prepaid account and a WBS, we received the following message:

 GL account 108000 cannot be used (Please Correct). 

Message no. ME045



Comparison of the field selection strings from the G/L account 108000 and the account assignment category P reveals that there is an incompatible combination of field selections for the field selectiongroup 'Network'.


The G/L account field selection is stored in table T004F; that for the

account assignment is stored in table T162K.



Please enter a correct G/L account.


  • In TC OBC4 what status field for GL do I select to compare with TCode OME9 status field for Account Assignment Category?


Can you please let me know what to compare in Account assignment Category field and GL account to ensure that these are in sync with each other.


Thank you

The first time Account 820290 was only created in FI as a primary expense.  After that this account was created in CO too as a secondary expense and any posting will appear an error: Account 820290 requires an assignment to a CO object

Question : How to correct this account back to FI only and not to appear in co?

Note :
Account 820290 requires an assignment to a CO object

You have not defined a CO account assignment for an account that is relevant to cost accounting.

System Response
Account 820290 is defined as a cost element.
This means that you must always specify a CO account assignment.

Enter one of the following CO account assignments

Cost center / cost center/ activity type
Sales order item (for a project or cost relevant)
Project / WBS element
Cost object (Process manufacturing)
Network/ Network activities
Business process
Profitability segment
Real estate object
The posting row affected is 000, account 820290.

First, if G/L account was created in FI, you can only create primary cost element in CO.

Secondary cost element can only be created if no account exists in FI.

Second, if you created the primary or secondary cost element in CO, you have to assign CO account assignment.

You can delete cost element in CO (KO04) if dependent objects found.

Third, when you create cost element in CO, documents would be also created in ‘Cost center accounting’ and ‘Profit center accounting’ when posing in FI. If no cost element exists in CO, no related documents would be created in CCA and PCA.
