Purchased parts are NOT affected by a cost implosion, only manufactured parts are.
However it is critical to note that the purchased and fabricated flags (in the settings area) DO NOT drive this behavior. The cost implosion behavior is driven by the Engineering Master field.
If this field is blank (NULL) then the part is considered purchased regardless of the purchased/fabricated check box setting. If the Engineering Master field is not blank (NOT NULL) then the part is considered to be fabricated and costs will be updated by the cost implosion function. This is true regardless of the purchased/fabricated check box settings.
So if you are getting ZERO costs on a part that has its PURCHASED check box checked, it is likely that:
- the part’s Engineering Master field is populated
- and that the EM exists (or it would throw an error during the implosion)
- and that the EM is empty (no operation or material cards)
- or that the EM is not empty but all the cards have zero qty / run rates or zero costs
