Hi Experts

   I am working on a requirement in crm web ui but i don't have enough experience for the subjetc, that's why I am asking for your help and asking all of you 2 questions:

how round trip mens and how it works, neither how to implement it, I would appreciate you could give me an example and source code  how to do it for get_i method

  I have another doubt, how  get_ methods are process or work in runtime?,  I don´t know how to pass a data to get_i method and how to  implement a flag in get_i method to disable a the field in runtime when you select in another field a value in a dropdown list

Thans a lot for your Help

Hi,

to disable a field during runtime, you can use loop at screen.

the parameter should be public, in order to access it,

FORM set_screen .

  IF Flag  EQ 'X'.

    LOOP AT SCREEN.

      IF screen-group1 = 'GR1'.

        screen-input = '1'.

        screen-invisible = '0'.

        MODIFY SCREEN.

      ENDIF.

    ENDLOOP.

Will try to answer your question :

how round trip mens and how it works, neither how to implement it, I would appreciate you could give me an example and source code  how to do it for get_i method

-> You can reffer to standard code on each webui component.

  I have another doubt, how  get_ methods are process or work in runtime?,  I don´t know how to pass a data to get_i method and how to  implement a flag in get_i method to disable a the field in runtime when you select in another field a value in a dropdown list

->How it's work, please try to create implementation for method get_XXX then put external break points and try to do transaction on WebUI, you will understand how it's work and it's behavior.

In CRM WebUI, i never pass a data into get_i method but i will read the data from BOL Layer using standard class. Please understand about BOL GeniL programming and all of related transaction such as : GENIL_BOL_BROWSER, GENIL_MODEL_BROWSER, GENIL_MODEL_EDITOR, etc.
