Dynamically changing the text on a screen

Former Member — Mon, 09 May 2005 17:58:39 GMT

Hello,

The requirement is to dynamically change the text of a text-element on a screen . I know that we can change the characteristics like visibility, input, output etc - of a element thro' the screen structure but do not know how to change the text displayed. I know that I need to do this in the PBO module but how is where I need help. How do you change the text displayed on the screen dynamically ?

Thanks,

Anu

Instead of using a "text elemnt" use an input field, make it output only. This will look like a "text element" but will allow you to fill it at run-time.

Hi,

I have no idea about changing the text element dynamically.

But you can refresh the screen by the following sample coding.

You can accomplish this with a RFC enabled Function module.

1. Create a function module. The only functionality will be to wait for 10 secs.

2. Create a subroutine which will set a user-command.

3. and at user-command call the function module.

Below is the code, I found on the web. It is quite simple..

DATA: ZNUM LIKE SY-TABIX.

: GET TIME.

: WRITE: /01 'Update Number:', ZNUM, SY-UZEIT.

: CALL FUNCTION 'Z_WAIT_30_SECS'

: STARTING NEW TASK 'IF'

: PERFORMING START_REFRESH ON END OF TASK.

: AT USER-COMMAND.

: IF SY-UCOMM = 'REFR'.

: SY-LSIND = SY-LSIND - 1.

: ADD 1 TO ZNUM.

: GET TIME.

: WRITE: /01 'Update Number:', ZNUM, SY-UZEIT.

: CALL FUNCTION 'Z_WAIT_30_SECS'

: STARTING NEW TASK 'IF'

: PERFORMING START_REFRESH ON END OF TASK.

: ENDIF.

: *----

: */ Program Subroutines

: *----

: FORM START_REFRESH USING TASKNAME.

: *----

: *

: SET USER-COMMAND 'REFR'.

: ENDFORM. "

: FUNCTION Z_WAIT_30_SECS.

: *"----

: ""Local interface:

: *"----

: DATA: ZTIME LIKE SY-UZEIT.

: GET TIME.

: ZTIME = SY-UZEIT + 30.

: DO.

: GET TIME.

: IF SY-UZEIT >= ZTIME.

: EXIT.

: ENDIF.

: ENDDO.

: ENDFUNCTION.

Hope this helps.

Design them as labels on the same position, display only one at a time on screen (Depending on a condition).

Thanks Rich. You sent me down the right direction.

I will try the other options suggested later. I logged in yesterday and saw Rich's response and went back to work on it thinking -'Duh!' Did not see the other options. Will try them now.
