@here Client I am dealing with has a FP001 (Finished Cake). WIP001 is the crepe that goes into ASSY001 which goes into FP001. Phantoms are not working - the GL impact appears correct - but the inventory is off. When I test building 100 - it should take 100 cake boxes out of inventory - only taking 1. Any thoughts off the top of your heads? Do both the ASSY and WIP need to be marked Phantom to work or just the ASSY? Is it a check both boxes on the record "Phantom" and Use Phantom Assembly need to be checked?
