Some of the calendar views are not displaying data while others are working fine. The ones that are not working, display the message:
No details available for the selected period
The offending views do not have any primary resources associated with them on the plan, which is why the message generates.
To add a primary resource to the view, please follow this link.
If there are tasks for the view (e.g. relevant details for the Day, Week, Month and Timeline views), an enhancement has been made in Workspace Apps version 1.0.21. This will be automatically upgraded for Access Evo users.
