I am looking for an advice to the following issue working in a report like the one below. My table contain a column Users (type text). Those users belong to two main groups and perform many movement in the ERP. So in the Visual level filter I would like to insert two groups instead of select each time all users =< "98999" and => "99000" selecting one by one. How can I create two groups and put one of them in the visual level filter? Thanks

Yes. Once you have a row level value for group, you can create your hierarchy easily within in the "axis" of the visual. "Group"-->"User"
