I believe you reused the cals for another users who do not used the cals and asign cals to them. If this is scenario you have to check weather user uses cals or not because it takes 24 hours to recall the cals after deletion until it is in the quarantine. Also you have to manually delete the cals and asign them.
Well my manager says hes been doing it for years and is not in breach of a license agreement. Is there a way i can get an official letter from QlikView showing otherwise. Can others confirm your statement please
