BEx Query Designer allows users to define queries on data in SAP Business Warehouse (BW) by selecting characteristics and key figures from InfoProviders. Queries can be parameterized and data selection can be restricted by characteristic values, intervals, and hierarchy nodes. Once defined, queries can be saved and executed in BEx Analyzer or on the web. The tool provides functionality to open, modify, find, and filter existing queries defined on various types of InfoProviders in BW, including InfoCubes, ODS objects, and InfoSets.
