If I understand... you have a section access and works fine after reload, close document and open again, is it correct?, well if it's true it's a normal behaviour of qlikview because when you reload again all data is reload (in QV desktop) and all data is performed so you have to close and open again this document to see your "reduce data".
If you prgram a task in QMC and specify an admin user and password, you can see data associated to a rol of a declared user.
Data reduction is performed when you open a document. If you decide to reload a document that is already open, you'll have access to all of the data because no more data reduction.
In a server environment, a reload is usually performed by a service that will only open-reload-save a document (e.g. as your ADMIN account without link to the data). By default, AccessPoint users don't have any reload options so this problem will not happen in a server environment.
You can simulate the same behaviour in QV Desktop by:
- performing reloads with the admin account only from the command line (with options /r or /p i think)
- removing reload privilege from the USER role, so that users can only open a document but cannot refresh the data.
