Hello,

In this case, you should master-detail construction instead grouping. Please check the sample report:

Hello,

For business objects only prepare additional object(master data) which will contain grouped data main level.
for any other data sources, you can create virtual source (Data from Other Data Source) with necessary grouping.

Thank you.

Hello,

In your case, with business objects, directly in the report - it is not possible. You should create an additional business object which will contain only grouped dates.

Thank you.
