How to disable automatic profit center assignment from WBS in PR under OPEX?

[former_member396266]

We are using work breakdown structures (WBS) to keep track of budgets and actual costs for certain projects. Sometimes such project will have cost from CAPEX or OPEX. When we raise purchase requisitions from SAP and assign account assignment (typically A for CAPEX and K for OPEX), we would like to assign a WBS to track budget and actual cost usage when this PR is related to this project. In the case of OPEX, we will enter both the cost center and the cost account, as well as the WBS. Currently the default mechanism of SAP will assign the profit center to the account assignment based on the WBS, which is a hidden field.

Upon goods receipt, SAP generates an account document which debits the cost account under the cost center we entered, but also put it under the profit center of the WBS. For the credit side, it is the GR not invoiced G/L account (a balance sheet) account and also under the same profit center of the WBS.

For the credit side it is fine. But for the debit side, the assignment of this profit center affected many of our reports. Our current config assign the same code as the profit center to the cost center and many of our reports treats profit center similar to cost center. The debit line created in this case has different cost center and profit center which caused problems to many of our reports.

We would like to see if it is possible to change the profit center of this debit line which based on cost account to use the same value as the cost center.

Are there any configuration to help to suppress the automatic profit center assignment from WBS in the purchase requisition when it is OPEX?

Thank you.

Hi

Please check if you can use the BADI, MB_DOCUMENT_BADI / MB_DOCUMENT_UPDATE to change the profit center for your specific scenario,

Thanks & regards

Hi

This is a standard design that profit center is defaulted from the real cost object, which in your case is a WBS Element. The posting to a cost center would be statistical in nature. If however,you want to replace profit center from WBS to one from Cost Center, you can use substitution rule with an user exit to do that. The below wiki link should help you on substitution.

Hi Sanil,

Thanks for your reply.

I have thought about this as well. I tried to use substitution under "Financial Accounting" -> "Line Item" level to replace the profit center. I debugged and this substitution works. However, after the profit center value is assigned. The profit center is changed back to the one from the WBS.

I then tried to use substitution under "Financial Accounting" -> "Complete document" level to replace the profit center. For some reasons this is NOT triggered. I am still wondering.

On the other hand, I am also looking into the project system configuration but it is not easy to understand...

Thank you.
