Inventory: Part Variants or Properties Within a Range of Real Numbers
My company is investigating the possibility of using Odoo 12 to track its inventory of raw materials. These are generally various kinds of sheet and bar stocks. They are procured in reasonably standard sizes, but once cut or modified, child pieces can reenter inventory at non-standard sizes.
Example: we buy a bundle of 20 120" lengths of 1"x1" aluminum tube. An order calls for 10 lengths cut to 115.75" and 10 lengths cut to 75.1875", and we fulfill it. The scrap from the first 10 are 4.25" long and can be recycled, but we'd like the other 10 pieces, each 44.8125" long, to be placed back in inventory to be used on a different order.
What we think we want: The ability to define a property/attribute of a part that can be any real number between two values. In the case of the example above, between 120" (the stock length) and 12" (the threshold for recycling).
I understand that there are extensions for the Inventory app that will populate a variant list in a step-wise fashion to emulate this function. Unfortunately when it comes to something like a sheet good, where you have length, width, thickness, and color, there are millions of possible variants for one sheet good when you get the physical measurements down to a useful resolution (in this case, maybe 0.05").
Has anyone else had to combat this inventory challenge while using Odoo? If so, did you use the part variant function provided by Odoo, or did you have to do some other customization to get a smooth and flexible system to work?
