Please see the scenario :
Requirements of raw materials for procurement are coming through MRP.
Suppose MRP proposed a requirement for 15 March -07 for a material 'x' based on the planned delivery time .
The vendor doesn't supplied the material on 15th March -07 .
It will be supplied on 20th March-07.
Also please note MRP runs daily at midnight in background .
1. So how this will effect the MRP ?
2. Any changes should be made in the PO by procurement dept ?
