    HI Venkat,

    For that u need to enhance ur view and then enhance the context node and redefine the particular atrribute get method.

    In the get_method pass the default value in to the field VALUE.

    To get the atrribute details in the UI select the field and press F2.

      Hi,

      In the Get_V method of your attribute fill the values in the ddlb table as shown below

      Data:lt_ddlb type bsp_wd_dropdown_table,
              lr_ddlb type REF TO cl_crm_uiu_ddlb.
      
            ls_ddlb-key = ' 1'.
            ls_ddlb-value = 'X '.
            APPEND ls_ddlb TO lt_ddlb.
      
            ls_ddlb-key = '2 '.
            ls_ddlb-value = ' Y'.
            APPEND ls_ddlb TO lt_ddlb.
      
      lr_ddlb->set_selection_table( lt_ddlb ).
      
          rv_valuehelp_descriptor = lr_ddlb.

      In the Get_P method of the attribute place the below code for deop down

      CASE iv_property.
          WHEN if_bsp_wd_model_setter_getter=>fp_fieldtype.
            rv_value = cl_bsp_dlc_view_descriptor=>field_type_picklist.
        ENDCASE.

      Hope this helps.

      Regards,

    Hello Venkat,

    If its a Search Object, you can do so by redefining the DO_PREPARE_OUTPUT method by checking the condition IV_FIRST_TIME = 'X' and defaulting the value of the search attribute here.

    Below is the sample code:

    
      DATA: lr_entity TYPE REF TO cl_crm_bol_entity.
      DATA: lr_query_service TYPE REF TO cl_crm_bol_query_service.
      DATA: ls_qs TYPE  crms_query_knoart_btil.
      DATA: lr_qs TYPE REF TO cl_crm_bol_dquery_service.
      DATA: lr_col TYPE REF TO if_bol_bo_col,
            lr_ent TYPE REF TO if_bol_bo_property_access,
            lr_search_node TYPE REF TO cl_bsp_wd_context_node_asp,
            lr_iterator  TYPE REF TO if_bol_bo_col_iterator ,
            lr_param     TYPE REF TO if_bol_bo_property_access,
            ls_selection TYPE genilt_selection_parameter,
            lv_attr_name TYPE name_komp ,
            lv_attr TYPE string,
            lv_low       TYPE string,
            lv_value_set TYPE abap_bool .
    
      IF iv_first_time =  'X'.
    
        CALL METHOD super->do_prepare_output
          EXPORTING
            iv_first_time = abap_false.
    
    * Set default status 
        lv_attr_name  = 'STATUS'.
        lv_low        = 'Z....'.
    
    * fetch the search node and its content.
        lr_qs = me->get_current_dquery( ).
        lr_col = lr_qs->get_selection_params( ).
    
    * check the currently visible search attributes.
        lr_iterator = lr_col->get_iterator( ).
        lr_param    = lr_iterator->get_first( ).
    
        WHILE lr_param IS BOUND.
    *           get the parameters
          lr_param->get_properties( IMPORTING es_attributes = ls_selection ).
          IF ls_selection-attr_name = lv_attr_name   .
    * SET_PROPERTIES
            ls_selection-low = lv_low .
            CALL METHOD lr_param->set_properties
              EXPORTING
                is_attributes = ls_selection.
            lv_value_set = abap_true .
            EXIT.
          ENDIF.
          lr_param = lr_iterator->get_next( ).
        ENDWHILE.
    
        IF lv_value_set EQ abap_false .
    * it was not part of the visible attributes, then add it at the end.
          CALL METHOD lr_qs->add_selection_param
            EXPORTING
              iv_attr_name = lv_attr_name
              iv_sign      = 'I'
              iv_option    = 'EQ'
              iv_low       = lv_low.
        ENDIF.
    
    * for a proper display of the added / changed attribute.
        lr_search_node = get_dquery_cnode( ).
        lr_search_node->build_parameter_tab( ).
    
      ELSE.
    
        CALL METHOD super->do_prepare_output
          EXPORTING
            iv_first_time = abap_false.
    
      ENDIF.
    

    Above is the sample code to default the value of a search attribute in a Search Page of a Knowledge Article.

    Even If its another BOL Object such as a BP Header View or Some Business Transaction View , you can still redefine the DO_PREPARE_OUTPUT method by checking the condition IV_FIRST_TIME = 'X'.

    Also, make sure that the user is creating this BP/transaction for the first time. You can do so by comparing the GUID at BOL runtime instance with the database.

    I hope this helps.

    Thanks

    Vishal
