Refurbishment order - cost allocation

Hi all,

In my refurbishment orders I have two different cost blocks.

1. worker performance

2. machine performance

The worker performance is not the problem. The work will be confirmed via IW42.

But the machine performance is the problem:

In the refurbishment order is the number of parts/materials.

The idea is that I have a customizing table where I can see the costs for a specific machine per part.

Example: Order with quantity 8 and 3 operations

010 - Maschine1

020 - only Human

030 - Maschine3

Machine performance = 8 x Maschine1 + 8 x Maschine3

For each operation there will be a human performance confirmed (IW42). The machine costs should be confirmed automatically.

So I need one work center for the human performance and different work centers for the machines.

How to calculate and confirm the machine costs in the SAP standard?
