How to lock supply( PO's or ITO's) against demand loaded in Supply Planning constrained plan
There are many instances where where business might want to lock supply to a particular demand. For example, lets say 260pcs are lined up for Org A but if the Org B demand is brought forward to an earlier date then these 260pcs would re-peg to ORG B and will not wait for original request to get reserved with Org A . If we have committed these 260pcs to ORG A and they must be sent there, it should not be pegged to Org B.
We would want to lock the supply so MRP doesn't repeg next time it runs.
