Display Instructor and virtual classroom

Summary/Content:

We are building up some reports in OTBI for learning. In these reports we want to have a more or less complete view on the learning item and its enrollments. So we want to see the courese, offering and activity data. For the activity date we are interested in the virtual class room url and the instrcuture on activity level. Unfortunally, the field is empty (these are the field i wants to use:   "Workforce Learning - Learning Management Real Time"."Worker (Instructor)"."Display Name" s_24;  "Workforce Learning - Learning Management Real Time"."Worker (Instructor)"."First Name" s_25)

Maybe my filter will break it
