Hi Andre,
Sincere apologies for delay.
1. As per you first query:-
The Atom feed you are referring is not the feed that describe the report. It is the feed that contains the data the report was made to access.
This is the feature that states that when you use a 2 level aggregation, we force an on-demand or lazy loading behavior. So you can only see the first parameter at the URL.
You need to save that report firstly to access the actual definition of the report and therefore how the urls for accessing the data are generated to have to access to this kind of feed by the below URL-
Note: You can find the report id at the bottom of the report(left side) once you have saved the report.
2. As per your second query:- Results are vary because of the different parameters.
The actual generated URL (from the RSS feed) contains only first parameter, which gives the results (as well sum of the instances) accordingly and after adding parameter manually, result are coming in multi-group.
Hope this helps you. Kindly let us know if have any query.
