Hi,

hi I have faced similar problem because when u make a field obligatory and if we again use at-selection screen event the error message can not be avoided

Define a form statement which checks whether the field is initial..

try this code, based on the radio button clicked the block appears & disappears, hope this helps

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.

PARAMETERS : P_FILE(25) TYPE C,

O_FILE(25) TYPE C.

SELECTION-SCREEN END OF BLOCK B1.

*Selection Screen 2

SELECTION-SCREEN BEGIN OF BLOCK B2 WITH FRAME TITLE TEXT-002.

PARAMETERS: CAL_TRA RADIOBUTTON GROUP G1 USER-COMMAND FLAG,

SESSION RADIOBUTTON GROUP G1 DEFAULT 'X'.

SELECTION-SCREEN END OF BLOCK B2.

*Selection Screen 3

SELECTION-SCREEN BEGIN OF BLOCK B3 WITH FRAME TITLE TEXT-003.

PARAMETERS: MODE DEFAULT 'X' MODIF ID BL1,

UPDATE DEFAULT 'X' MODIF ID BL1.

SELECTION-SCREEN END OF BLOCK B3.

*Selection Screen 4

SELECTION-SCREEN BEGIN OF BLOCK B4 WITH FRAME TITLE TEXT-003.

PARAMETERS: SES_NAM TYPE APQI-GROUPID MODIF ID BL2,

KEP_TRAS TYPE C DEFAULT 'X' MODIF ID BL2,

LOC_DATE TYPE SY-DATUM MODIF ID BL2,

USER TYPE SY-UNAME DEFAULT SY-UNAME MODIF ID BL2.

SELECTION-SCREEN END OF BLOCK B4.

************************************************************************

• At Selection-Screen Output *

************************************************************************

AT SELECTION-SCREEN OUTPUT.

IF CAL_TRA = 'X'.

LOOP AT SCREEN.

IF SCREEN-GROUP1 = 'BL1'.

SCREEN-ACTIVE = '1'.

ENDIF.

IF SCREEN-GROUP1 = 'BL2'.

SCREEN-ACTIVE = '0'.

ENDIF.

MODIFY SCREEN.

hi

i think u can write the same validation code in ur program under

at selection-screen output on field

event

[jayanthi_jayaraman]

Hi,

FInd the parameter/Select-options used in the standard program.

Then in main program,check for that.You can find the validation related to that.

Other way is,simply put /h after you entered values.Then check in program, where the cursor is going.From there in program,copy the coding.

declare the same naming conversion of the standard and include this <b> saprck23</b>

program, so that you don't want write the validation logic ... it will take care of it ...

becuase saprck23 has the AT SELECTION-SCREEN ON VALUE-REQUEST ...

hi girish,

as per ur suggestion, actually what i shud declare??

im not able to get wat u said....

can u explain it in detailed manner pls??

[Former Member]

Hi,

The validation for POSTING PERIOD is done by AT SLECTION_SCREEN in the prog SAPRCK23.

If u wantto use teh same logic, then search for" AT selection-screen " in the program and just copy-pase the logic, taking care of all naming conventions of variables followed by standartd sap program.

Revert back if any issues,

Reward with points if helpful ,
