CO history update with Profit centers

Hi Experts,

I am having a problem. I want to update the CO documents originating in CO by Production order confirmation, which uses secondary cost elements.

The direct way is to update the Production orders with the PCA and run 1KEA. However, I was wondering if there is a user exit which could be called during 1KEA.

Could someone throw some light. Thanks.
