Well.. that's up to your client.
But if people responsible for posting stock get that confused between three lines on the inspection stock posting screen they really need to do some serious employee training. You can remove all the line except those three if you want. Not a problem.
I don't know what the reporting concern is. QA32 can already give you a report of where stock was posted to in a pretty easy to use form that can then be exported to Excel if you need to anything really fancy with it.
Normal material documents are posted in the background so any reports based on material documents should be fine.
