Use AT SELECTION-SCREEN. Try this:

 DATA: g_kunnr TYPE kna1-kunnr,
       g_name1 TYPE kna1-name1.
 
 PARAMETERS: p_kunnr LIKE g_kunnr,
             p_name1 LIKE g_name1.
 
 AT SELECTION-SCREEN.
 
   " Select Customer Name
   IF p_kunnr IS NOT INITIAL.
     SELECT SINGLE name1
       FROM kna1
       INTO g_name1
      WHERE kunnr EQ p_kunnr.
 
     IF sy-subrc EQ 0.
       " pass the value to parameter
       p_name1 = g_name1.
     ENDIF.
   ENDIF.
 
 AT SELECTION-SCREEN OUTPUT.
   " make the parameter P_NAME1 inactive.
   LOOP AT SCREEN.
     IF screen-name EQ 'P_NAME1'.
       screen-input = 0.
       MODIFY SCREEN.
     ENDIF.
   ENDLOOP.

Hi,

" AT selection-screen "  is the event which gets triggered for any action in the selection-screen. For a particular field it will be "at selection screen on <field-name>".

You can write the code or select query based on the event and the function code which comes during the actions.
