Problem using relations

Hello,
I have a problem using a complex report: when I add a databand to my subreport, the data of this subreport is no longer displayed in the output.
I attach the data to the post. In the report "TestWithoutMerkmal" all works as desired. In the report "TestsWithMerkmal" I have added databand "Databand1" to subreport "subreport_Verhaltensaufrufe_der_Aktivität" . This databand has a parent component and a relation assigned. But now the data of "subReport_Aktivität_zu_Komponente" and its subreports is no longer displayed.

I suspect the problem is caused by the fact that on this subReport I use the same datasource "Merkmal" with a different relation. Is it possible to get around this?
Thanks
Clemens

Yes, you're right.

Unfortunately, it a restriction of our engine: you cannot use the same data source for detail bands.
As a workaround, you can create a copy of your Merkmal datasource, for example Markmal2, and use this new datasource for detail bands.

Thank you.
