We set up our "formula" (base) parts to be based on 1 unit. So, in our case, if our "formula" looked like:

10% Mtl A

20% Mtl B

65% Mtl C

5% Adhesive

We configured the part's method as 1 pound (LB) units:

1 LB = 0.10 LB Mtl A

0.20 LB Mtl B

0.65 LB Mtl C

0.05 LB Adhesive

In our case, we went a step further. We would never make individual pounds of the product so we have the "formula" part configured as a Phantom BOM. So Part A's method would call for 1000 LBs of the "formula" part. When the job is created, the formula gets exploded out as follows:

Part A, 1 EA = 100 LB Mtl A

200 LB Mtl B

650 LB Mtl C

50 LB Adhesive

------

1000 LB

I hope I explained this OK and I hope it helps.
