[Former Member]

Hi friends,

i have 4 radio buttons on the selection screen

PARAMETERS :
          r1 RADIOBUTTON GROUP g1 DEFAULT 'X' USER-COMMAND DEV,
          r2 RADIOBUTTON GROUP g1,
          r3 RADIOBUTTON GROUP g1,
          r4 RADIOBUTTON GROUP g1.

PARAMETERS :

   file1  TYPE rlgrap-filename MODIF ID A1,   
   file2  TYPE rlgrap-filename MODIF ID A2,  
   file3  TYPE rlgrap-filename MODIF ID A3,   
   file4  TYPE rlgrap-filename MODIF ID A4,   

Iam using loop at screen and displaying one file1 when r1 is active on the selection screen

simlarly

file2 when r2 is active on the selection screen

file3 when r3 is active on the selection screen

file4 when r4 is active on the selection screen

Its working fine.. perfect.

But my problem is i need to provide F4 help for all files dynamiaclly

ie :

when file 1 is active then i need to provide f4 help using at selection screen on value request for file1

when file 2 is active then i need to provide f4 help using at selection screen on value request for file2

when file 3 is active then i need to provide f4 help using at selection screen on value request for file3

when file 4 is active then i need to provide f4 help using at selection screen on value request for file4

iam using the following code but its showing me some error

can any one correct it and let me know.

data :
  w_file      type rlgrap-filename.


 if R1 = 'X'.
  W_FILE = 'FILE1'.
   ELSEIF R2 = 'X'.
   W_FILE = 'FILE2'.
  ELSEIF R3 = 'X'.
   W_FILE = 'FILE3'.
  ELSEIF R4 = 'X'.
   W_FILE = FILE4'.
ENDIF.


AT SELECTION-SCREEN ON VALUE-REQUEST FOR W_FILE.

Its showing me error " On Value Request Shoud Be Follwed By Paramter Or Select option -low or High "

How Can i pass the file name based on the radio button check for AT selection screen on value request Event

Hi

U need to use that event four times for every "file" parameter:

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE1.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE3.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE2.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE4.

but u can define a routine to be used for all above events

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE1.
   PERFORM GET_FILE USING FILE1.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE3.
   PERFORM GET_FILE USING FILE2.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE2.
   PERFORM GET_FILE USING FILE3.
AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE4.
   PERFORM GET_FILE USING FILE4.

Hi MAX,

Very Thanks For your answer.... I was just looking for any other alternative instead of calling the event 4 times.

Cheers...

          R4 RADIOBUTTON GROUP G1.

PARAMETERS : FILE1  TYPE RLGRAP-FILENAME MODIF ID A1,
             FILE2  TYPE RLGRAP-FILENAME MODIF ID A2,
             FILE3  TYPE RLGRAP-FILENAME MODIF ID A3,
             FILE4  TYPE RLGRAP-FILENAME MODIF ID A4.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE1.
  PERFORM GET_FILE USING FILE1.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE2.
  PERFORM GET_FILE USING FILE2.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE3.
  PERFORM GET_FILE USING FILE3.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR FILE4.
  PERFORM GET_FILE USING FILE4.

FORM GET_FILE  USING    P_FILE.
  CALL FUNCTION 'KD_GET_FILENAME_ON_F4'
    CHANGING
      FILE_NAME     = P_FILE
