The Active and Availability fields are not editable on the Resource List grid view after upgrading to PPM Clarity 15.5.1. This occurs for all users. However, the users are able to edit these two fields on the resource properties. The Allow Grid Editing option is checked for these two fields and there are no secure subpages or display conditions on any of the of the subpages for all resource and role types.
Component: PPMSTU : CA PPM STUDIO
The root cause of this issue remains unknown, but changing the 'Attribute Value Protection' setting under Administration - Objects - Resource - View - Resource List : Options will allow the Availability and Active fields to be editable on the Resource List grid view. The setting was updated to 'Display all attribute values on this list'.
