When looking at a Marketing List then from the navigation selecting Marketing > Quick Campaigns, the default view is Quick Campaigns Associated View. When selecting a campaign receive Error page, Error has occurred. Tested the other views and all work except for the BulkOperations Associated View, receive the same error when opening. Looking into each view and the dependencies, both are missing the Activity / activityid dependency.
Not sure how this happened. A couple of months ago completed the upgrade from CRM 4 to CRM 2011 RU13. Not sure if the issue was there before the upgrade. Wondering if reapplying RU 13 will resolve the issue or if there is another way to add the Activityid dependency.
