The radiobuttons are not a genuine feature of ALV grid lists but are simulated using the corresponding icons and the HOTSPOT_CLICK event. *& Report ZALVGRID_WITH_RADIOBUTTONS *& *& This program shows how to realize radiobuttons in ALV grid lists *& using event HOTSPOT_CLICK. *& *& Screen 100: *& - Flow logic *& *& PROCESS BEFORE OUTPUT. *& MODULE PBO SAP AG 3
