You can use page property 'NumberOfCopies' and set the datasources using code (with property 'PageCopyNumber' you know which page copy is actually printing).

I can't understand your problem. Can you explain it in more detail please? Because this is the normal use case of master-detail reports: one instance with 1 or more related sub-instances. Databand1: Source = Meeting Databand2: Source = Location, Relation = Link from Location to Meeting, Master = Dat...

You need both. Master Component will not work without a relation.

You can use a 3rd, intermediate databand for location.

Databand1(Meeting) -> link to Databand2(Location) -> link to Databand3(Meeting).

Databand2 do not show any information (height = 0).
On Databand3 you have to filter out the current meeting of Databand1

2) Use property 'Start Angle'

use 'General'

{Maximum(DataSource.Column1, Maximum(DataSource.Column2, DataSource.Column3))}

Thank you

4) Create a new page. Select the report (e.g. in property grid). Undo/Redo is not available. You have to select a component/page first.
