Re: Strange Happenings in PMP03

Upon investigation, I believe that I've found the cause/solution to this 
negative PO problem, and INfor, if you're listening, this is a free one for you 
too.
 
The problem arises for locations running MRP and Vendor Scheduling. If a 
purchased item is set-up as vendor scheduled on it's Item/Stockroom record(s) 
and it's being planned by MRP, the system can't handle MRP exception messages 
(Reschedule In/Out, Change Qty., etc.). The system wants Vendor Scheduling to 
do all the schedule/quantity changes. All the negative PO quantities that I 
have seen were for VS items with MRP exception messages on 12/MRP. The key to 
running cleanly is to make sure no exception messages are produced in MRP by 
using the right MRP Filter on page 2 of the Production Details record and, of 
course ensuring that those filters are correctly set-up in the WTYP parameters 
in 11/MDU. VS can use the 11A, 12A, 13A, 14A, and 19A filters. All these 
filters should have all zeros (no exceptions) in the +-C and IO fields. You 
must also have an 'A' on the Production Details Filter field (leaving it blank 
will cause the non-VS filters (11, 12, etc.) to be applied to the MRP run.
 
Finally, after making the above filter changes, the next run of MRP will remove 
the existing exception messages. You should have no more new PO negatives 
introduced.

We do requisitioning and approvals.  We have had some issues with the 
order quantity going negative, but we have not been able to pinpoint what 
the problem is.

Ray,
You are the first I've heard of someone using requisitioning.  Do you do
approvals also?

Has anyone had any experience with the PMP03 Order Quantity and
Outstanding quantities being set to negative when a receipt is done for
another PO for the same part? I have noticed that the PMP17 requisition
Order Qty. for the received PO line is negative. We are creating
non-blanket POs from requisitions.
