Hi Abhishek,
In case you are having MM-QM stock not in sync, you should try the SAP note 48815, as already suggested by Anand. One of the reason for having such an issue is already suggested by Craig. Once you run this report of the SAP note, before clearing the stock you will get the screen where you can see what all are not in-sync. So you can take informed decision here.
I still have a small doubt. Please can you also share the "Reference Field Monitor" setup, as shown below -
Note that this reference monitor will also help to understand the reference object (Inspection lot). You can see the F4 help on the traffic light in the output of QA32.
This will help to understand your issue better.
Thanks,
Arijit
