This answer is extremely disrespectful. You ignored the original poster's concern that changing the date received to before the assembly was created will result in inaccurate data in his company file about when the items were received. 

I have seen a pattern of answers like this where you and other administrators of the quickbooks community discussion either disregard the original poster's question or misunderstand their question and post links to FAQ articles that provide information that only a beginner would need  - not someone asking a complex question.
