I’m working on new Nav project , it’s steel fabrication (cutting welding and painting). the first problem i faced is how to manage cutting process : Cutting bars or Plates to many parts .
To solve the problem i’m thinking to create each part as items (Big number of parts) then create for each cutting operation a production order that has as input bars and toles and as output Parts
Welding process : Create an assemby itrem wich compesed of those parts .
But a little warning also. Using the manufacturing module does require that you’re are fully familiar with the module, as it is one of the most complex in NAV. It’s a big project just to implement this module.
I would say that your UOM should match your BOM. So if you in the BOM needs to specify KG, then use KG. If you specify a number of 12 meter bars, then use that.
as i understand the different parts varify only in a few properties. so i think best would be to define only few items, but add a couple of properties to table item: width, height, thickness, material, usage, color, and so on. you could also define some raw items (raw material), which are then the base for the used items. cutting, welding, painting are operations in routings. combined (base) items are managed using assembly Boms. in production orders you use als production BOMs.
