Reloading a Qlikview document with section access on the server will cause an error if you forget to define the NTNAME with the user account which runs the Qlikview services. Only with the NTNAME defined, Qlikview server can access the QVW for reloading.
But the problem is not a Section Access problem, but a problem with the NTFS-authorization.
On a specific folder with a specific qvw-document the settings are that the AD-group EVERYONE has access to the folder and the document in the folder, that is: all END-users should bee able to see and open the document from the Accesspoint. But for reason or another the accesspoint won't include the document in the doc-list unless the user is asigned specific access-rights.
Hope it's cleat what the problem is.
