problem with selection screen

[Former Member]

Hi everyone,

Im facing a problem in selection screen.

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

PARAMETERS: PDATE LIKE PA0000-BEGDA DEFAULT SY-DATUM.

SELECTION-SCREEN: PUSHBUTTON /33(15) APITEXT USER-COMMAND APA1.

SELECTION-SCREEN END OF BLOCK B1 .

SELECTION-SCREEN: BEGIN OF SCREEN 400.

SELECTION-SCREEN BEGIN OF BLOCK B3 WITH FRAME TITLE TEXT-100.

SELECTION-SCREEN BEGIN OF LINE.

SELECTION-SCREEN COMMENT 1(18) FOR FIELD PA1.

PARAMETER: PA1(5).

...

...

...

PARAMETER: PA100(5).

SELECTION-SCREEN END OF SCREEN 400.

SELECTION-SCREEN END OF BLOCK B3.

AT SELECTION-SCREEN.

IF SY-UCOMM = 'APA1'.

CALL SELECTION-SCREEN '400'.

ENDIF.

(ie) If i click on pushbutton it will call screen 400. My requirement is

if i enter a value in PA1 and if i click on execute button its leaving to

first screen, and from there i have to execute. I want it to get executed

in screen 400.

NOTE: Not using modify id.

Plz anyone solve this problem. Its vry urgent.

Hi

U need to check the sy-ucomm in the AT SELECTION-SCREEN event:

AT SELECTION-SCREEN.
IF SY-UCOMM = 'APA1' OR 
    ( SY-UCOMM = 'ONLI' AND NOT PAI IS INITIAL ).
  CALL SELECTION-SCREEN '400'.
ENDIF.
