-- [ Picked text/plain from multipart/alternative ] Both Mac & Ruben offered plausible solutions.... But the answer to our specific puzzler was: The Purchased Item that was showing unexpected De-expedite Messages was coded as an MPS Item ( IMRP field = "M" ). It had many parents, some of which were NOT coded as MPS Items. MPS generation runs first for only MPS items; found some demand for this purchased item & created a Planned order for this item ....All Is Well. Then MRP generation runs for all items ( MPS items and non-MPS items); it finds some more demand for the Item in question, also finds an existing Planned Order and suggests rescheduling that planned order. Solution? An MPS item should NOT have any parents, grandparents...that are NOT also MPS Items. Or another way to say it.... low level items probably ought to be MRP Items not MPS Items. In our case, someone used the "handy copy feature" in creating a new item number but copied an inappropriate item number.
