Recently one of the users, while accessing a few of the System User’s views, was getting the below error.
You do not have prvReadmsdyn_personasecurityrolemapping permission to access Persona Security Role Mapping records. Contact your Microsoft Dynamics 365 administrator for help.
There were a few System users’ views that were working fine.
The user had the Security Role = System Administrator, however, the Access Mode was set to Administrative.
Changing the Access Mode to Read-Write fixed the issue.
Hope it helps..
