Should I continue to use manual planning for blanket POs?
Most companies that extensively use blanket POs do so out of habit from previous systems because it is a common planning method in non-MRP systems. Blanket POs are incompatible with the master schedule and are not needed with MRP.
Blanket POs are essentially multi-bucket forecasts that are tedious to create and maintain and typically lead to over-stocking. With MRP you can replace blanket POs with a Demand Driven order policy and Supply Days setting that will trigger POs in regular supply days intervals based on actual net demand.
