Costs for external services not as variances in PP-PI order

Dear experts,

we use external services in our receipts. after PP order release pruchase requisition will be generated, transferred into Purchase Order with GR and IV. Everything fine so far.

Now we face a question if it is possible to post the costs for external services in the Actual costs instead of the Variances. Costs for the external service appears as variances in KKS2 TCode after calculation.

Is this possible at all?

If yes, what has to be done?

Many thanks in advance.

Best regards

Patrick
