Although Note 1110140 refers to this scenario not being possible, Note 1943804 suggest it is.
We have created a subcontract PO, created an inbound delivery and GR'd. This has performed a 107 mvt against the inbound finished product whilst at the same time down-dating the subcontract component stock at vendor via a 543 O mvt. So far so good.
The problem is that demand for the subcontract components is still being driven in by the finished product PO (as can be seen in the attachment).
Does anyone know how to solve this?
