I have a cl_gui_alv_grid table on the main screen. I need to open another screen at the touch of a button. There is a container on this screen. Inside this container, I want to display a filter window with all the fields from the table. The filter window looks like when we select the columns and click filter. And there we filter each field from and to. Tell me how it can be done. What is the name of the filter class object? How do I create it? What table of fields should I give it?
