How do we clear the allocation?
1) Verify there are no BOM production entries in the system
2) Verify if the Production Entry was deleted or Posted
3) If the allocation got hung up somehow, when the Production Entry was deleted the system must not have properly removed the record from the BM404 file. DFDM is currently the only way we can find to delete the allocation from the data file - file it's getting caught in BM404_ProductionTierDist.M4T
4) Final step is to run the Multi-bin Recalculation Utility
