The problem is:
We have a configuration, where we purchase component kits with purchase price = 0 (zero) from a subcontractor. Purchase component method used is customer order. The only cost connected to the Purchase order is a fixed assembly cost per unit, as the components are shipped F.O.C to the subcontractor.
Our problem is: when the P.O is received, the posting control type for the charges M65 (Purchase charges, not absorbed in inventory value) is used. And we would want it to be M187 (Purchase charges, absorbed in inventory value).
What dictates which posting control type/transaction code that is used?
And how can we set this up so that we get the posting control type we want (M187)?
