Issue with CALL SELECTION-SCREEN

Hi experts,

I am working on a report.

Here on the selection screen , based on the selection of some radiobuttons ,i want to call a secondary selection screen.

So i am using the following program code ,

AT SELECTION-SCREEN on BLOCk blk.

IF p_abc = c_x.

CALL SELECTION-SCREEN 100 STARTING AT 20 5.

IF sy-subrc <> 0.

MESSAGE text-011 TYPE c_e .

ENDIF.

ENDIF.

so currently , once i complete my slection on the screen 100 , the popup screen stays there and rest of the programing logic is executed correctly.

My issue is that , once i complete my slection on the screen 100, i want that the pop up should be closed

And then the the rest of the program logic should continue.

please guide me how ,this can be done.

Regards,

Rajesh Kumar.
