Thank you Maheswaran. So you believe that the cost center must not be entered together with the PM order, right?
So all costs should be posted on the PM order and then to be settled. However, i cannot understand how the system allows you to use two true cost objects at one posting (cost center and PM order).
Now, in KSB1 i have one line from the posting of the invoice and a second line from the posting of the settlement. Thus the amount is actually doubled.
