I have an assembly that is comprised of 2 raw materials that are cut to specific lengths and bonded together. The BOM in our MRP system show the raw materials as a material specification with a length for qty under the assembly. The assembly of the 2 raw materials is fully machined after bonding. I'm trying to determine what the best way of creating the assembly structure would be so that we can output the BOM to our MRP system. The catch is that we are trying to drive the creation of this part with DriveWorks which means we are staying away from configurations. The raw materials are cut to many different lengths and are used in many assemblies. So I'm really not sure how to get the BOM to come out correct if we are using the same raw material in multiple lengths without creating a new assembly to take the raw material and cut it to length, which adds many new part numbers based on length.
