We have a business requirement where we have Firm Purchase Orders and WIP jobs outside the planning time fence (PTF). We then have new demand for the item coming from SO. When we run MRP, the system is extending the planning time fence up to the Need by date of the latest PO so this means there will be no stock to cover the new demand and we are in backorder!
Item Leadtime: 5 days
PTF: 5 days
Sysdate : 09-Feb-2009
Firm Purchase Order: 20-Mar-2009 (outside the PTF for the item)
WIP job demand: 20-Mar-2009
New SO 5000001252 with schedule ship date 17-Feb-2009
To cover the demand for SO 5000001252 MRP is suggesting a new planned order for 20-Mar-2009.
Profile MRP:Firm Planned Order Time Fence = No
Overwrite = None
Append Planned Orders = Yes
Planning Time Fence Control = Yes
Has anybody come across this scenario? How can we force MRP to suggest a Planned Order for the 17-Feb-2009?
Can the above requirement be achieved with ASCP?
