when i receive inventory i need to record how many pieces, how many boxes, and how many pallets it came in. The problem is that the conversion between pieces, boxes, pallets is variable, every transaction it can be different so i cant use the units of measure to accomplish this. For example - on one transaction i can have 100 pieces in 2 boxes, next time it can be 100 pieces on 5 boxes etc. Does someone know the best way to do this?
