We have one part# for the cases we make for our machines.  The actual case is made outside to the print and then comes back for QC, then goes back out for paint and silkscreen.  I have tried all kinds of various ways of capturing these costs.  ie Make Part, Sub-assy, purchasee part.  For the last few years I have been manually going through P.O. to add the metal work and paint/silkscreen to get the standard cost.  Surely, there is a better, easier way!!!

Thank you.  I was hoping for someother way than adding more parts to the system.  But a person's got to do what a person's got to do to keep from going insane at year end.
 

You may have already solved your problem, but if I may throw in my 2 cents:  This is the perfect part to set up as an item type "M" (make from).  You still need a part number for the unfinished case and a seperate part number for the silkscreen product, but once set up, costs should be captured and rolled up automatically, both as standard cost and average cost.
 
We do many products this way and works well for us.
 
Hope this helps.
