Answer:
Hi Kum,
The Selection Screen can be manipulated with the AT SELECTION SCREEN OUTPUT event block . Example Code follows showing the enabling or disabling a field (LOCALFIL) on the condition of a Radiobutton (SHOW_LOC). Notice however the USER-COMMAND UCOMM addition to PARAMETERS statement.
* ==========================================
* SELECTION SCREEN DEFAULT
* ==========================================
PARAMETERS : SHOW_INP RADIOBUTTON GROUP GRP1 DEFAULT 'X'
USER-COMMAND UCOMM .
PARAMETERS : SHOW_LOC RADIOBUTTON GROUP GRP1 .
PARAMETERS : CONV_LOC RADIOBUTTON GROUP GRP1 .
PARAMETERS : LOCALFIL LIKE RLGRAP-FILENAME OBLIGATORY
DEFAULT 'C:\TEST\MARA.txt' .
* ========================================
* AT SELECTION SCREEN OUTPUT
* ========================================
AT SELECTION-SCREEN OUTPUT .
LOOP AT SCREEN .
IF SCREEN-NAME = 'LOCALFIL' .
IF SHOW_LOC = 'X' OR CONV_LOC = 'X' .
SCREEN-INPUT = 1 .
ELSE .
SCREEN-INPUT = 0 .
ENDIF .
MODIFY SCREEN .
ENDIF .
ENDLOOP .
Another Example to Check both low and high field of a select option follows where the AT SELECTION-SCREEN event block is used .
* ========================================
SELECT-OPTIONS : TYPEABSE for p2001-subty NO INTERVALS OBLIGATORY .
* ========================================
AT SELECTION-SCREEN .
IF TYPEABSE-high IS INITIAL .
MESSAGE e398(00) WITH 'Give the high value' .
ENDIF .
Hope these example help .
Good luck
