People that don't appear in SA won't see any documents. However, people that appear in SA but cause the data reduction to reduce data to nothing will still see the document in AP. On opening such an AP document, they will get "Failed to open..."
As long as QlikView relies security on the file system, make sure that in the Settings menu, Document Properties, Server tab, the "Filter AccessPoint Document List based on Section Access" is checked. So if either the user is not in a group with NTFS permissions on the file or it does not belong to a member of the group allowed in the NTNAME, the user shouldn't be able to see the document, even if he's allowed to get to the AccessPoint.
When security works with NTFS, there is no way to create that "customized" URL for each user. You should use / build a Single Sign On, and it might not be worth it, specially if the solution above works.
Hope that helps.
Thanks for the reply
Can you explain the Note section <in bold letters> ?
As per your example a person with SA but causes full data reduction will get 'Failed to open' pop up window
However, I am curious to know what are the cases when the user will be able to see the document even if the section access is not enabled for him and the option (Filter AccessPoint Document List Based on Section Access) is also selected .
Is it possible for such a case to exist ?
