bill of material
(OP)
When we initially release an assembly drawing, the bill of material (table-based Bill of Material) generated in solidworks is used by manufacturing as the item master used throughout the company.
Do you know what other companies are doing to control the integrity of the bill of materials?

RE: bill of material
My point? Engineering should drive the BOM, and the drawing is the perfect vehicle.

RE: bill of material
If the product is designed by engineering, it should be the BOMs that drive the ERP/MRP system. When purchasing or production make changes, innocuous as they may seem, bad things can happen. I know of what instances where production did exactly what I mentioned in my previous post; used non-structural bolts in a structurally critical area. This resulted in tens of thousands of dollars in lost hours and recalls.

RE: bill of material
If you have purchasing and other folks that are able to make a BOM change substituting a different part number for a lower grade bolt then you have something wrong with your change process. Engineering should be on the loop for the process and sign off on a change like that. If they just substituted lower grade bolts for the same part number then there is either a purchasing/mfg problem with reading a spec/drawing or there is a problem with the spec/drawing.
Either way those are both big no/nos and should be immediately corrected
