How to use OVS Search Help For Multiple Inputs

This Document helps you to create OVS Help for multiple inputs. 

Create WebDynpro Component with initial view and window.

Go to Component, under used component use WDR_OVS under componet with OVS Component use.

Goto view context create 2 attributes, VBELN and KUNNR.

Go to View Layout and create input fields for VBELN and KUNNR.

Go to Properties->Select input help mode to OVS and select OVS Component usage. Do the same for all attributes.

Go to Methods tab->Create OV_OVS Enent handler, by selecting Event as OVS.( What you created in First Step ).

Under ON_OVS method write sample code like below.

Sample Code :

method ON_OVS .

  types:
    begin of lty_stru_input,
      vbeln type vbeln,
    end of lty_stru_input.
  types:
    begin of lty_stru_list,
      vbeln type vbeln,
    end of lty_stru_list.

  types:
    begin of lty_stru_input1,
      kunnr type kunnr,
    end of lty_stru_input1.
  types:
    begin of lty_stru_list1,
      kunnr type kunnr,
    end of lty_stru_list1.

  data: ls_search_input  type lty_stru_input,
        lt_select_list   type standard table of lty_stru_list,
        ls_search_input1 type lty_stru_input1,
        lt_select_list1  type standard table of lty_stru_list1.

  FIELD-SYMBOLS : <ls_selection>  type lty_stru_list,
                  <ls_selection1> type lty_stru_list1.

  CASE 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.

      IF ovs_callback_object->context_attribute CS ‘VBELN’.
        SELECT vbeln
               FROM vbak INTO TABLE lt_select_list
               WHERE ernam = sy-uname.
        ovs_callback_object->set_output_table( output = lt_select_list ).

      ELSEIF ovs_callback_object->context_attribute CS ‘KUNNR’.
        SELECT kunnr
               FROM kna1 INTO TABLE lt_select_list1
               WHERE ernam = sy-uname.
        ovs_callback_object->set_output_table( output = lt_select_list1 ).
      ENDIF.

    WHEN if_wd_ovs=>co_phase_3.

      IF ovs_callback_object->context_attribute CS ‘VBELN’.
        ASSIGN ovs_callback_object->selection->* TO <ls_selection>.
        IF <ls_selection> IS ASSIGNED.
          ovs_callback_object->context_element->set_attribute(
                                 name  = `VBELN`
                                 value = <ls_selection>-vbeln ).
        ENDIF.
      ENDIF.
      IF ovs_callback_object->context_attribute CS ‘KUNNR’.
        ASSIGN ovs_callback_object->selection->* TO <ls_selection1>.
        IF <ls_selection1> IS ASSIGNED.

                                 value = <ls_selection1>-kunnr ).
        ENDIF.
      ENDIF.
  ENDCASE.

endmethod.
