I created a new role called medical administrators
My motive is to allow the user role to create/edit/delete the medical records
I went to the custom entities tab and selected "Create, Read, write, Delete, append, append to" against the custom entity.
But when the user tries to access the CRM environment they get the below message
Insufficient Permissions
You do not have permission to access these records. Contact your Microsoft Dynamics CRM administrator.
What else should I add for the particular user group?
