Databinding Master/Detail Include option missing

[Heinz]

I' am watching your video for create Master/Detail with 2 Datagrids

So I add first datagrid to my page and in Data-property of grid I enter "${getFertigungsauftraegesResult}" (this is my master-table)

But I see no option to include other tables like shown in your video.

Most probably you do not have any one-to-many relationships related to this master table.

yes, this was the problem
