I need some guidance regarding how to manage 2 different parts that are produced from the same raw material and operation. These are not co-parts, they are not created at the same time. Sometimes when the process is run we get an A quality product and other times we get a B quality product.
Most often our requirements call for the B part, however, we produce more of the A part than the B.
We can use the A in a job the requires the B, but we can not use the B in a job that requires the A.
We currently use only 1 part number and the team in inventory, manually tag the product that qualifies as the “A” material.
How can we set this up so that we are accurately recording the inventory if we move to 2 part numbers?
How do we prevent MRP from requiring more production if we have enough to cover demand, because we can use A in place of B?
