Webdynpro enhancement: how to hide fields?

[paul_bakker2]

Hi,

I only have limited experience with ABAP Webdynpro enhancements - mostly adding fields and changing their values.

Question: is it possible, using Webdynpro enhancements, to 'hide' standard fields in a view or to make them 'read only'?

I checked the particular fields I want to change, but the 'visible' and 'enabled' attributes are not bound to a context element.

So it seems unlikely, but has someone perhaps found a clever way of doing it?

thanks in advance

Hi,

The simple way is using Personalization. Check this document for reference which suits your requirement: http://scn.sap.com/docs/DOC-49108

Esle,

You have to enhance the WDA view and remove the UI element and create a new UI elements and bind the read only property.

Hope this helps u,

Thanks for your reply and that link.

I don't think Personalization is the answer - doesn't that just allow end users to change their screens?

I see now that you can use Component Configuration to hide fields or deactivate them, but I actually want to do this programatically (ie turn the field on in some cases, off in others).

So I guess I need to use Enhancements. But how exactly do you delete/hide/deactivate a field using WebDynpro enhancements? With most SAP enhancement concepts you can only add items.

cheers

Hi Paul,

You can do the property settings of view ui elements in POST EXIT of method WDDOMODIFYIVEW( ).

Please refer the below code:

Scenario: to hide the standard view fields  SECONDTITLE_LBL & SECONDTITLE_DDLB which are inside the transparent container PERSONALDATA.

  IF first_time = abap_true.

    DATA container TYPE REF TO cl_wd_uielement_container.

    DATA children TYPE cl_wd_uielement=>tt_uielement.

    DATA element TYPE REF TO cl_wd_uielement.

" get the container reference in which ui elements are embedded

    container ?= view->get_element( 'PERSONALDATA' ).

" Get the children of that container

    children = container->get_children( ).

"Loop over elements

    LOOP AT children INTO element.

      DATA id TYPE string.

     " get ui elment id

      id = element->get_id( ).

      IF id = `SECONDTITLE_LBL` or id = 'SECONDTITLE_DDLB'.

        element->set_visible( `01` ).                                           " set the property visibility of ui element

      ENDIF.

    ENDLOOP.

ENDIF.

-------------------

Similarly use the method SET_READ_ONLY, to set the property READONLY

Hope this helps you.

Hi Paul,

In Post exit of WDDOMODIFYVIEW use this code

data enable type ref to cl_wd_input_field.

  enable ?= view->get_element( 'INPUT_FIELD_ID' ).

enable->set_enabled( abap_false ).

Hi Paul,

In Post exit of WDDOMODIFYVIEW get ui element and change the value as you like.
