Modifying Selection screen dynamically

[Former Member]

Hi guyz

herez another question

Can we modify selection-screen dynamically as we do in case of screen

What i want to do is

I want to display one parameter as checkbox and when user ticks this box I want to display another one

If we are defining two checkboxes earlier and making one invisible than can we modify selection screen to display another check box

Thanks in advance

Rashmi,

Yes you can do that.

Attach a MODIF ID with all the fields that you want to modify at runtime. Write the code AT SELECTION SCREEN, to LOOP at SCREEN and make it visible.

Take a look at this example.

REPORT EVENT_DEMO.

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME.

PARAMETERS: R1 RADIOBUTTON GROUP RAD1 DEFAULT 'X',

R2 RADIOBUTTON GROUP RAD1,

R3 RADIOBUTTON GROUP RAD1.

SELECTION-SCREEN END OF BLOCK B1.

SELECTION-SCREEN BEGIN OF BLOCK B2 WITH FRAME.

PARAMETERS: R4 RADIOBUTTON GROUP RAD2 DEFAULT 'X',

R5 RADIOBUTTON GROUP RAD2,

R6 RADIOBUTTON GROUP RAD2.

SELECTION-SCREEN END OF BLOCK B2.

AT SELECTION-SCREEN ON RADIOBUTTON GROUP RAD1.

IF R1 = 'X'.

MESSAGE W040(HB).

ENDIF.

AT SELECTION-SCREEN ON RADIOBUTTON GROUP RAD2.

IF R4 = 'X'.

MESSAGE W040(HB).

ENDIF.

Hi Ravi

Using Modif id in case of selection-screen how we will make a field invisible and than again visible as structure sscrfields doesnt have any such component named Invisible so we can not make it visible or invisible by assigning value 0 or 1.

plz correct me if am not in right direction.

Hi Rashmi,

Just have a look at this sample code.

Parameters: chk1 type c as checkbox,

chk2 type c as checkbox modif id 'ID1'.

**then

AT SELECTION SCREEN.

LOOP at SCREEN.

IF screen-group1 = 'ID1'

if chk1 = 'X'.

screen-invisible = ''.

else.

screen-invisible = 'X'.

ENDIF.

modify screen.

ENDIF.

ENDLOOP.

This code may have syntax error, but i think you can do away with them.

**IF this is helpful, reward points

Thanks Vaibhav and Ravi

Rashmi,

Don't give a value 0. Do it like screen-invisible = ' '.
