We have a Vendor Consignment Warehouse that we use pull sheets to move inventory from. Unfortunately, in CSI, if a work center is short material, it will automatically backflush from the Vendor Warehouse if it is the only one that has stock. We do not want to turn off backflushing - we just don't want it to pull from the Vendor Consignment Warehouse. Instead, it should just make the work center go negative. I have been told this will require a customization. Has anyone done something like this and have some pointers to get me going?
