Testing the latest update
I am seeing an ugly problem with the "B" setting when entering a partial. It happens on components where the qty per is anything other than 1. The correct quantity is being issued (verified in IN-E) but some screens are showing screwy numbers. In IN-A, the On hand, Allocations and WIP are incorrect. WO-A quantity issued and % are wrong. JC-A, % issued is wrong. Because onhand is wrong, got a false shortage report. MRP is using the wrong onhand & allocations.  
 
Running Reconcile Inventory SM-J-C, Master and Transactions level, Method B, corrected the actual inventory. Then needed to run Recalculate Inventory Book Value UT-K-G The SM-J-C report had many "Location had trxns with UOH of xxx but BKICLOC UOH was yyy; chgd BKICLOC UOH" messages.
 
Running WO-K-H Recalculate Work Order Cost fixes the IN-A  WIP and Allocations. Also the WO & JC screens. Correct allocations now being used by MRP.  The WO-K-H is great, but in this case, running it was masking the problem in inventory.
 
Guess we'll be sticking with the "Y" default for a while longer.

Under Work Order Defaults (SD-B). Backflush in Enter Finished Production.

I just sent Cyndee an updated version.  I think we got all the kinks worked out but if anybody else is interested, I can send them a copy as well.

Lynn, thanks for the prompt response. Unfortunately, the 8/23 file did not fix it. I've sent you details by email.
