Hiding Standard SRM Webdynpro View UI elements InputField) at runtime

[Former Member]

Hi Friends,

Here i am trying to hide View UI elements in SRM 7.0 standard application, for this i have written code in WDDOMODIFYVIEW under Pre-Exit . But once i run application, first time written code is not effecting( Fields are not hiding), but if i do some action on the screen, fields are hiding.

Can someone help me, how can i hide UI elements first time itself?

Below code i have written : Here i am hiding First name & Last name Input fields

  if first_time = ' '
 DATA lo_nd_employee TYPE REF TO if_wd_context_node.

  DATA lo_el_employee TYPE REF TO if_wd_context_element.
  DATA ls_employee TYPE wd_this->Element_employee.
  DATA lv_firstname TYPE wd_this->Element_employee-firstname.

* navigate from <CONTEXT> to <EMPLOYEE> via lead selection
  lo_nd_employee = wd_context->path_get_node( path = `DATA.EMPLOYEE` ).

* @TODO handle non existant child
 IF lo_nd_employee IS INITIAL.
 ENDIF.

* get element via lead selection
  lo_el_employee = lo_nd_employee->get_element( ).
* @TODO handle not set lead selection
  IF lo_el_employee IS INITIAL.
  ENDIF.

CALL METHOD LO_ND_EMPLOYEE->SET_ATTRIBUTE_PROPERTY
  EXPORTING
    ATTRIBUTE_NAME = 'FIRSTNAME'
     PROPERTY       = 1
    VALUE          = SPACE.
*    INDEX          = USE_LEAD_SELECTION
*    ALL_ELEMENTS   = ABAP_FALSE
    .
CALL METHOD LO_ND_EMPLOYEE->SET_ATTRIBUTE_PROPERTY
  EXPORTING
    ATTRIBUTE_NAME = 'LASTNAME'
     PROPERTY       = 1
     VALUE          = SPACE.
*    INDEX          = USE_LEAD_SELECTION
*    ALL_ELEMENTS   = ABAP_FALSE
end if.
    .

Thanks

Hello Sandeep,

just remove the condition " if first_time = ' ' ". This condition wont be satisfied for the first time. thats the reason your logic works if you trigger the roundtip.

Hello Sandeep,

if you face the same problem even after removing the condition, then i think in the WdDoModifyview, the attribute properties are reset by the standard coding. Try moving your code to post-exit instead of pre-exit.

code seems to correct. Make sure once again that you do not have first_time condition checked.

Further it is good practice to have the code ,using the defined constants.

CALL METHOD LO_ND_EMPLOYEE->SET_ATTRIBUTE_PROPERTY
  EXPORTING
    ATTRIBUTE_NAME = 'FIRSTNAME'
     PROPERTY       = IF_WD_CONTEXT_ELEMENT=>E_property-visible
    VALUE          =   abap_false .

    .
CALL METHOD LO_ND_EMPLOYEE->SET_ATTRIBUTE_PROPERTY
  EXPORTING
    ATTRIBUTE_NAME = 'LASTNAME'
     PROPERTY       =  IF_WD_CONTEXT_ELEMENT=>E_property-visible
     VALUE          = abap_false .

Hi Saravanan,

Even i tried same like moving code from Pre-exit to Post-exit, but there is no change in output.

Hi Baskaran,

i checked once again First_time condition, i removed that condition. even i changed code as per your guidelines.. but still same output.

Thanks

it should be beacause of this condition only.

check it properly and activate the comp again.

if first_time = ' '

also could you please provide the name of the Standard comp u r working on.

Thanks
