When you attempt to configure Limited Data Access on the current SmartBox Object that is already part of a policy where the current SmartBox Object is excluded, the following error is thrown:
Error 547, Level 16, State 0, Procedure SetSecuredByObjectToNone, Line 49The DELETE statement conflicted with the SAME TABLE REFERENCE constraint "FK_Smartbox_PolicySmartObject_Smartbox_PolicySmartObject". The conflict occurred in database "K2", table "Smartbox.
There is no workaround at this stage. This is scheduled to be addressed in a future update.
