How to clear Selection Screen input

After executing a report, the green arrow back key will takes us back to the selection screen with the original input on it.

However, my client would like to see the selection screen without any previous input on it, so he could start entering new input without deleting/overwriting the old ones. Is it possible to do that?

Any hints will be greatly appreciated.


Use this part of code:
----------------------
DATA: EXECUTED TYPE N.

your data definitions starts here

AT SELECTION-SCREEN OUTPUT.
IF EXECUTED = 1.
EXECUTED = 0.
CLEAR: var1, var2, etc.
REFRESH: selop1.
here you have to clear all your parameters, select options etc.

ENDIF.

START-OF-SELECTION.
EXECUTED = 1.
your main coding starts here.
END-OF-SELECTION.
