is-it possible to create a data from other datasource business objects or from a cross-tab which is defined with business objects?

Thanks

Hello.

Please, send us your report template with sample data for analysis.

Thank you.

I join an asp project. Put the file datasource.mrt in C:, or modify the Impression.aspx code.
Call the page http://localhost/StimulsoftSupport20151 ... ssion.aspx
In the template, i create a data from an other datasource in ordre to create a data with the groupName and the count of line by group.
In the first data band the projects are listed
In the second data band the data from other datasource is listed but nothing is displayed...
Can you help me?

PS : I try it with 2013.3 and 2015.2 version.

Thanks in advance

Hello.

Unfortunately, it's impossible to create Data source from Business objects.
You could try to register your business objects with RegData() method.

Thank you.
