We make individual passes through all levels. First, a Forecast that generates requirements for our top level Finished Goods. Then subsequent passes through each level down to Raw Materials. Each pass is complete when all Make/Buy messages are satisfied with real Work Orders or Purchase Orders. I can ignore something if I wish to and let the balance go negative. In our method, Planned Orders don't help. I can see their value in a single pass type of scenario. I just haven't been able to fine tune things well enough to have confidence in it. To be clear, the messages - Make, Buy, Expedite, Delay, Review, etc... will be marked and printed every time MRP is run, but planned orders will not be generated.
