How to Use OVS Help For Multiple Input Fields in Select-Options.

This Document helps you to create OVS Help for multiple inputs in Select-Options.

Step 1 : Create WD Component with view and window.

Step 2 : Go to component, under used components use WDR_SELECT_OPTIONS and WDR_OVS as Components with SELECT_OPTIONS and OVS as Component use, as like below screenshot.

Step 3 : Go to view->properties tab->click on create controller usage.

Step 4 : Select OVS and SELECT_OPTIONS Component. 

Step 5 : Go to view layout->create view container ui element.

Step 6 : Go to Window->Right click on created View container, here VC-> Click Embed View.

Step 7 : F4 on view to be Embeded->Select WND_SELECTION_SCREEN View.

Step  8 :  Go to  view WDDOINIT method-> Go to code wizard-> Select Instantiate used component->Click F4 Select Select_options.

Step 9 : Go to code wizard->Select  Method call in Used Controller->Select Component WDR_SELECT_OPTIONS.

Step 10 : Select Method Name-> INIT_SELECTION_SCREEN.

Code in WDDOINT Method after Method call.

Click on Pattern->Select ABAP Objects Pattern->Give Interface name IF_WD_SELECT_OPTIONS.

Select Method->SET_GLOBAL_OPTIONS.

Replace ME object with Interface Controller reference lv_r_helper_class .

Change all Exporting Parameters to ABAP_FALSE. If you want any button required on selection screen make it abap_true.

Again go to pattern->Select CREATE_RANGE_TABLE Method.

Replace ME object with Interface Controller reference lv_r_helper_class .

And add code like below.

Create  another range table for KUNNR.

Complete Sample Code in WDDOINT Method.

method WDDOINIT .
*– Instantiate the used component –*

  data lo_cmp_usage type ref to if_wd_component_usage.

  lo_cmp_usage =   wd_this->wd_cpuse_select_options( ).
  if lo_cmp_usage->has_active_component( ) is initial.
    lo_cmp_usage->create_component( ).
  endif.

  DATA lo_INTERFACECONTROLLER TYPE REF TO IWCI_WDR_SELECT_OPTIONS .
  lo_INTERFACECONTROLLER =   wd_this->wd_cpifc_select_options( ).

  DATA lv_r_helper_class TYPE ref to if_wd_select_options.
  lv_r_helper_class = lo_interfacecontroller->init_selection_screen( ).

  CALL METHOD lv_r_helper_class->SET_GLOBAL_OPTIONS
    EXPORTING
      I_DISPLAY_BTN_CANCEL  = ABAP_FALSE
      I_DISPLAY_BTN_CHECK   = ABAP_FALSE
      I_DISPLAY_BTN_RESET   = ABAP_FALSE
      I_DISPLAY_BTN_EXECUTE = ABAP_FALSE.

  DATA : rt_vbeln TYPE REF TO data.
  DATA : rt_kunnr TYPE REF TO data.

  CALL METHOD lv_r_helper_class->CREATE_RANGE_TABLE
    EXPORTING
      I_TYPENAME     = ‘VBELN’
    RECEIVING
      RT_RANGE_TABLE = rt_vbeln.
  lv_r_helper_class->add_selection_field(
    i_id              = `VBELN`
    I_DESCRIPTION     = ‘Sales Document’
    i_value_help_type = if_wd_value_help_handler=>co_prefix_ovs “OVS Help
    it_result         = rt_vbeln ).
  FREE rt_vbeln.

  CALL METHOD lv_r_helper_class->CREATE_RANGE_TABLE
    EXPORTING
      I_TYPENAME     = ‘KUNNR’
    RECEIVING
      RT_RANGE_TABLE = rt_kunnr.
  lv_r_helper_class->add_selection_field(
    i_id              = `KUNNR`
    I_DESCRIPTION     = ‘Customer’
    i_value_help_type = if_wd_value_help_handler=>co_prefix_ovs “OVS Help
    it_result         = rt_kunnr ).
  FREE rt_kunnr.

ENDMETHOD.

Step 11 : Go to Methods->Create OVS Event Handler->Under Event click F4->Select ON_OVS Event for Select Options.

Step 12 : Under this method write code like below.

Sample code :

method OVS.
 
  IF i_ovs_data-m_selection_field_id = ‘VBELN’.
    OVS_VBELN( i_ovs_data ).
  ELSEIF i_ovs_data-m_selection_field_id = ‘KUNNR’.
    OVS_KUNNR( i_ovs_data ).
  ENDIF.
endmethod.

Step 13 : Now we have to write code to get OVS for both VBELN and KUNNR.

Step 14 : Go to Methods tab-> create two methods OVS_VBELN and OVS_KUNNR.

Step 15 : Go to OVS_VBELN Method->Create Importing Parameter

I_OVS_DATA  TYPE  IF_WD_SELECT_OPTIONS=>T_OVS_DATA.  And Write code for OVS_VBELN.

Sample Code OVS_VBELN.

method OVS_VBELN .

  types:
    begin of lty_stru_list,
      VBELN type VBELN,
    end of lty_stru_list.

  data: lt_select_list   type standard table of lty_stru_list,
        ls_select_list   type lty_stru_list,
        fieldname        TYPE string.

  field-symbols:       type lty_stru_list,
                      TYPE lty_stru_list,
                 TYPE STANDARD TABLE,
                           TYPE table,
                              TYPE data.

  case i_ovs_data-m_ovs_callback_object->phase_indicator.

    when if_wd_ovs=>co_phase_0.
    when if_wd_ovs=>co_phase_1.
    when if_wd_ovs=>co_phase_2.

      SELECT VBELN FROM VBAK
             INTO TABLE lt_select_list.

      i_ovs_data-m_ovs_callback_object->set_output_table( output = lt_select_list ).

    WHEN if_wd_ovs=>co_phase_3.
      ASSIGN i_ovs_data-m_ovs_callback_object->selection->* TO .
      ASSIGN i_ovs_data-mt_selected_values->* TO .
      fieldname = i_ovs_data-m_selection_field_id.
      ASSIGN COMPONENT fieldname OF STRUCTURE TO .
      INSERT INTO TABLE .
  endcase.
endmethod.

Step 16 : Repeate step 15 for OVS_KUNNR.  Add Importing Parameter, in code declare kunnr field types and fetch kunnr in select query.

Output :
