Chanti,
UD does not necessarily mean that you will do stock posting. A lot may not be stock posting relevant.So, no quality stock does not ensure that you do not have any usage decision pending.
I am again repeating my earlier response:
1. Go to QA03
2. Provide lot number 500044164
3. Press Enter.
4. Click on the blue [i] button beside the System status, user status row (marked in red):
5. Please let us know the active status values.
Best Regards,
Rajen
