Sry, let me rephrased my question. I need to remove the access for clients as I am planning for a decommission of QlikView dashboard. However, I want to keep my scheduled tasks running as per normal in case clients want to activate the dashboard again.
Why don't you just remove those users from the dashboard distribution list. So that they wont be seeing in Access Point in the next refresh. However, you can leave your task trigger as is so that it will reload as scheduled but will not distribute to users.
