Reading screen attributes at runtime

[Former Member]

Hi all,

i want to read screen attributes (e.g. is the field editable or not) in abap. But i can't find a way to do that.

i know the fm RS_SCREEN_IMPORT  or  RPY_DYNPRO_READ  but these functions do only read the static attributes of the screen (Table D021S). But i need the attributs at runtime (including if they where modified by MODIFY SCREEN at PBO).

Has anyone a solution to this issue?

Thanks a lot.

Hi,

If you want to check the screen attributes at run time. You can use the LOOP at Screen.

Check the structure of the 'SCREEN'

Use loop at Screen for check the attribute of each field

Hi Andre,

Just to elaborate, in module pool programming, you can set screen field property in PBO. For that you use LOOP statement and a runtime table, SCREEN. This contains screen fields and their attributes.

Do not forget to use MODIFY screen.

you can use loop at screen .    endloop.

this will let you to process all the screen attribute.

thanks for your answers.

in deed i can edit and read the attributes directly in the pbo by "loop at screen".

the problem is, that i need to read the values in another screen.

In screen B i need to read the attribute of screen A. and it is not possible to read the attributes in the PBO of screen A, because it is an standard screen. i can not "loop at screen" and read the current value.

i hope i could describe my problem more specific.

Hi Andre

You can store the attributes of Screen A in PAI via some implicit enhancemnt and then when PBO of your screen triggers you can read it..

Please provide program and screen number

I think I did not read that in the post and I thought you wanted to read same screen.

Hi Andre,

You can use loop at sceen.  endloop in the event at selection-screen output.

In between you can use the different variables from structure screen.

For example.:-

   LOOP AT SCREEN.
      IF screen-name    EQ 'S_TXT04' OR
        screen-group1  EQ 'ID1'.
        screen-active = '0'.
        MODIFY SCREEN.
      ENDIF.                           " IF screen-name    EQ 'S_TXT04' OR
    ENDLOOP.                           " LOOP AT SCREEN.

Here it searches for screen name is eq to S_TXT04 or its group is equal to ID1.

if it matches then screen fields with group ID1 will be active.

Like screen-active you can use these variables as well:

NAME

GROUP1

GROUP2

GROUP3

GROUP4

REQUIRED

INPUT

OUTPUT

INTENSIFIED

INVISIBLE

LENGTH

ACTIVE

DISPLAY_3D

VALUE_HELP

REQUEST

VALUES_IN_COMBO

COLOR

I did solve the problem by saving the data in the PBO of screen A (by loop at screen) in an internal talbe and read this stored data in screen B

thanks a lot for your help!

Hi Andre,

Export the screen attributes in PAI of first screen and import them again in next screen call.

Thanks
