Any way to have Negative Inventory in Forward or Backward Flushing situations? Customer wants consumption to occur before PO receipt (and therefore go negatvie)
Not as standard.
Navision insists you have the items in place so it can post through the appropriate costs. If you are backward flushing this should not matter anyway if you are not using routing link codes, the flushing will occur once the work is “finished” and therefore you must have had the stock in to have finished the work.
If this is the case it is packaging etc I would recommend you manually flush the stock, you can do this prior to the full completion of the order. If you are insistent on going negative you will need to modify the system.
