Sorry no experience with Costpoint Brandon. You might have to look at the import capabilities of Deltek. Or go to a third party like Razorleaf or xLM and see if they can come up with a solution.
I stumbled across your post while on a google search today. I'm not sure if you've found a solution or are looking for one still. I am an ex Deltek data migration and integration consultant with 15 years experience having done precisely what you are looking for, amongst many other things related to integration, automation, redesign, mass loads, splits, merges, etc. I have a very strong background in Deltek manaufacturing from the technical perspective and have done much work with product definition, boms, inventory and integration. IF you'd like to discuss your ndeds with me, just let me know. I'd be happy to brainstorm with you and see if what you want to do is something we might work on together. Or I may just be able to give you some advice on solving your quest.
Just let me know either way. Sorry I didn't see your post sooner when you posted it.
