On the PUR detail page, the check box "Restricted to contract scope" is unchecked by default.
It would be a great idea to have it check by default!
"Restricted to contract scope?" must be checked in order to have the contract scope taken in account.
If not checked the contract scope is not taken in account and the resulting compliance report is wrong.
Furthermore, it is not possible to update the PUR when the related article has been linked to a license:
The property 'Limited usage rights (contract scope)' cannot be changed because there already are or there have been licenses for this product use right. (ASP-D8)
