Finished good A is made from subassemblies B, C, and D. When creating a production order for A, the B, C and D lines are indented showing they are subassemblies. I have B and D in stock, so I don't need to make them. I'm using advanced warehousing so raw materials are picked from bins and brought to the production bin for consumption. I can't get BC to recognize the subassemblies I have in inventory and consume them instead of picking the lower-level raw materials. I've tried moving the subassemblies to the production bin for consumption and they aren't recognized by the production order. Has anyone found a way to use existing inventory this way?
