We use Business Explorer (BEx) which is part of SAP GUI and is a “built in” function to MS Excel. The BEx Analyzer is the query development portion, where you develope queries. We save queries as workbooks in user roles, and depending upon the query, depends on which role we save it to. We use the BEx Browser to log into the BW system, which shows BW in a more graphical (more GUI) manner. The queries (workbooks) assigned to roles show up as icons in BEx Browser, and the user just points and clicks to execute the query. The results automatically pop up in MS Excel. You can also access BEx Analyzer by entering transaction code RRMX in BW.
