Reposting Existing COPA line items with new Profit center

Hello SCN,

Could you please advise how to repost the exiting COPA line items replacing old profit center with new profit center?

The scenario is - we have thousands of COPA line items are posted with incorrect profit center. We want to repost all the existing COPA documents with new Profit center.

I have explored the option of KE26 but due to the volume of data to be corrected are huge, would like to know another option?

Billing Documents are showing Profit Center - 100

FI documents are posted with Profit Center - 100

COPA documents are Posted with Profit Center - 100

With the above case, I would like to Change the COPA documents with correct profit center 101.

I think KE4S too would not solve the problem since while running KE4S with the option reverse and repost the COPA documents, the new documents which will be posted will have the same old profit center as Billing document and FI documents contains the old profit center.

Any help is greatly appreciated.

Thanks in advance!
