Raw material data collection

We have been thinking about the AMM module for material data collection in MES, but that is really the only function we are looking to get out of it. Has anyone been able to get that ability without AMM even if it means stripping down the Job entry screen or something? Any thoughts? I hope my explanation makes sense.

To put it in a scenario. We make paper bags, a roll of papers weight is known in the system and written on the side of the roll. Warehouse takes the roll out to the floor, they use some of the roll and then want to record the new weight at the machine.
