The formula cannot be simple as the cost of an assembly is the sum of the cost of the individual components.
What about the labour cost to assemble the component.
Also the cost of an assembly is not necessary the product cost.
Costing is a bit more complex than that. That why we have specialized system such as ERP.
What is good to do is to get the cost from ERP, instead of trying to develop algorithms to do it in PDMLink.
Saying this, there is the cost estimate during the design phase that needs to be considered
we 've got some quite complex Cognos report for design phases (ie the WTpart does not exists yet in ERP) where we use mBOM, related MPMProcessPlan , Times set in MPMOperations and type of Workcenters to estimate a price ....
