In-House repair in CRM

Dear Experts,

We have requirement to process In-house repair from CRM system. In our scenario we are creating Return for Repair for the Return request . This item is triggering sales order in SD where inbound processing is done.

After analysis, Technician will decide to perfrom some repair work with service parts. No. of Hrs required & quantity required are planned in same transaction. Item category used for repair work is REPA & service parts RMAT.

We are using Single -Object Controlling where controlling scenario is already maintained. The issue is for the planned service work & service parts , the plan revenue & cost is not updated in internal order.

Also checked in controlling integrationcock-pit but it has no messages. Pls guide me what is missing in setting item category.

Regards
