UPDATED 11/11/2020:
In 2020x FD03, the IP Protection Classification app transitioned the access check from the Policy to an Interface Rule. This change allows for additional object Types to be Classified out of the box and improves performance for non-protected data.
However, following the upgrade of the 3DEXPERIENCE environment containing the IP Protection Classification app to 2020x FD03 (and beyond), additional steps must be performed to enforce access restrictions on existing classified data.
From MQL, as an Admin user, the following commands must be executed:
MQL>> transition interfacerulesflag;
MQL>> execute prog emxECLMigration -method addEXCExceptionInterface;
