What we do is put
finished part RIM, TIRE & BEARING in the BOM for
finished part WHEEL.
Then we issue one workorder for the number of WHEELs we want and use material issues to relieve inventory of the RIMs, TIREs & BEARINGs used.
Any shortages of RIM, TIRE & BEARING are purchased or manufactured separately.
Note: Purchasing
finished part items was discouraged by DBA technicians because they've setup type
R for purchased items. We continued this way because it's easier for our people to consider F as Finished parts and R as Raw materials.
