Hi,

AT SELECTION-SCREEN .... OUTPUT is the event corresponding to PBO of your dynpor's. Here you can initialize the values to your screen fields also you can use LOOP AT SCREEN to change the attributes of screen fields liek hiding the screen field etc.

LOOP AT SCREEN.

IF SCREEN-NAME = 'FIELD1'.

SCREEN-INVISIBLE = '1'.

MODIFY SCREEN.

ENDIF.

ENDLOOP.

AT SELECTION SCREEN OUTPUT is PBO and AT SELECTION SCREEN is PAI.

you can also use AT SELECTION SCREEN ON for specific fields which is similar to FIELD MODULE in your flow logic of normal dynpros.

AT SELECTION-SCREEN OUTPUT event is PBO event in Reports ( Type 1)

Before the selction screen dislpyed to the user, it gets executed, no of times selection screen is displayed, the same number of times this block gets executed.

Screen modifications can be done under this event by using SCREEN structure.

Hope this may be useful.

it is used when u want to change ur selectiion screeen parameters dynamically depending upon the one or two parametrs at ur selection screen..

like u can say if one checkbox is selected then a input field shud appera on screen and when it is unchecked that field shud also be invisible..

TABLES : SSCRFIELDS,mara.

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

SELECT-OPTIONS : S_MATNR FOR MARA-MATNR.

PARAMETERS : R1 RADIOBUTTON GROUP RB1 DEFAULT 'X',

R2 RADIOBUTTON GROUP RB1,

R3 RADIOBUTTON GROUP RB1,

R4 RADIOBUTTON GROUP RB1.

SELECTION-SCREEN PUSHBUTTON /10(20) FRST USER-COMMAND FRST.

SELECTION-SCREEN PUSHBUTTON /10(20) SCND USER-COMMAND SCND.

SELECTION-SCREEN END OF BLOCK B1.

DATA : ACTIVE1 VALUE '1',

ACTIVE2 VALUE '1'.

initialization.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF SCREEN-NAME = 'R1' OR SCREEN-NAME = 'R2' .

SCREEN-INVISIBLE = ACTIVE1.

MODIFY SCREEN.

ENDIF.

IF SCREEN-NAME = 'R3' OR SCREEN-NAME = 'R4' .

SCREEN-INVISIBLE = ACTIVE2.

hi

these are the options

AT SELECTION-SCREEN.

Extras:

1. ... ON psel

2. ... ON END OF sel

3. ... ON VALUE-REQUEST FOR psel_low_high

4. ... ON HELP-REQUEST FOR psel_low_high

5. ... ON RADIOBUTTON GROUP radi

6. ... ON BLOCK block

7. ... OUTPUT

at selection-screen output is the PBO of selection screen .

i.e. it will trigger before showing the selection-screen.

and others are PAI i.e after user interaction for the perticular things.
