This only a question that how do you implement your "change management"?
Such as the engineering change or designing change?
So, there are 2 ideas for your reference:
1. Were the parts follow your customer's order or not? if yes, apply for your customer to except. if not, you must scraped your inventories.
2.If the parts revised, did your engineers release the ECN(engineering change notice) to you? did it show that how to deal the inventories? if it is no, you may check your procedures about your QMS.
