It is possible to test out section access in QV desktop. Once you reload the dashboard, you need to close QV completely, then reopen the dashboard. It should prompt you for credentials. Be careful though, because if your section access code is bad, you could end up locking yourself out of the dashboard and losing any unsaved work!
Yes, it is possible. In any case, since you're using NTNAME, you only can login as yourself.
Possible reasons that you see all data:
- "Initial Data Reduction Based on Section Access" is not checked.
- It is checked, but "Strict Exclusion" is not checked and region AMS doesn't exist.
I always recommend to use "Initial Selection Based on Section Access" instead of Data Reduction for testing purposes - you can see what Section Access is doing. When you know it works, switch to Data Reduction.
