can not re-read production order's PP master data(WM related)
I met below problem.
I set up the PP-WM interface, an outbound delivery will be created after I release the production order. But if I delete the outbound delivery(the delivery is not posted), I can't re-read the production order's PP master data,error message:"Transfer requirements have already been generated, so therefore the bill of material cannot be read." Can't create the delivery again via LP10. Can't issue materials directly to production order via MB1A, error message:"Document 1000033 / 0000000586 does not contain any selectable items".
Can advise how to solve this problem? Any setting is wrong?
