This is the first time I am setting up project stock, so I must be doing something wrong! I have a project stock in plant A (big qty, special stock Q) that I want to transport to plant B by means of a intra-company stock transport order (UB order).
I have created STO with item category U and account assignment Q (the same WBS element that exists in plant A with high stock). No problem in the STO, but when I am trying to create the delivery, the systems says that only 0 pieces are available.
I have also put high qty in the warehouse stock (no special stock) in the same storage location in plant A and tried STO without account assignment (warehouse stock) - this one works okay.
What can be the reason? It seems like the ATP check looks in a "wrong place", e.g. in another storage location.
If you don't have an idea what can be wrong, maybe you know how I can check what the system is checking (where to debug or some kind of log)? We run ATP check in ECC (not APO).
Many thanks in advance,
