WDA-FPM-4-用OVP做查询跳转到明细

转载：https://www.cnblogs.com/sapSB/p/10100697.html

前面做了查询的UIBB配置，在这边可以直接复用，查询的feeder class也就自动复用了。

1.给查询的feeder class添加接口，继续继承form的接口。

2.挨个实现每个方法，即使是用不到的也点进去激活。

  method IF_FPM_GUIBB_FORM~GET_DATA.
    CS_DATA = gw_table.
  endmethod.

  method IF_FPM_GUIBB_FORM~GET_DEFINITION.
    DATA:gt_data TYPE TABLE OF zhsb_order_index.

    eo_field_catalog ?= cl_abap_tabledescr=>describe_by_data( gw_table ).
    mo_catalog = eo_field_catalog.


    "action 参数是控制UIBB参数映射的EVENT定义。这里可以定义回车事件，下拉事件等
  endmethod.

3.给search的事件处理方法中添加跳转的事件(给选择单号的事件)：

  METHOD if_fpm_guibb_search~process_event.
    DATA:lt_where TYPE rsds_where_tab.
    DATA:lt_order TYPE TABLE OF zhsb_order_index,
         ls_order TYPE zhsb_order_index.
    DATA:lc_para TYPE REF TO cl_fpm_parameter.
    DATA:ls_value TYPE string.

    DATA:ls_result TYPE zhsb_order_index.


    IF io_event->mv_event_id = if_fpm_guibb_search=>fpm_execute_search.

      TRY .
          CALL METHOD cl_fpm_guibb_search_conversion=>to_abap_select_where_tab
            EXPORTING
              it_fpm_search_criteria = it_fpm_search_criteria
              iv_table_name          = 'ZHSB_ORDER_INDEX'
              io_field_catalog       = mo_catalog
            IMPORTING
              et_abap_select_table   = lt_where.
        CATCH cx_fpmgb.
      ENDTRY.

      SELECT * FROM zhsb_order_index INTO TABLE lt_order UP TO iv_max_num_results ROWS WHERE (lt_where).
      IF sy-subrc = 0.
        LOOP AT lt_order INTO  ls_order.
          MOVE-CORRESPONDING ls_order TO ls_result.
          APPEND ls_result TO gt_table.
        ENDLOOP.
        ev_result = 'OK'.
      ENDIF.

    ELSEIF io_event->mv_event_id = 'FPM_RESULT_SEL'.
      DATA : lo_event TYPE REF TO       cl_fpm_event,
             lo_fpm   TYPE REF TO       if_fpm.

      READ TABLE gt_table INTO gw_table INDEX 4.
      lo_event ?= cl_fpm_event=>create_by_id( 'FPM_CHANGE_CONTENT_AREA' ).

      lo_event->mo_event_data->set_value(
        EXPORTING
          iv_key   = 'TARGET_CONTENT_AREA'
          iv_value = 'PAGE_2'
      ).
      lo_fpm ?= cl_fpm=>get_instance( ).

      lo_fpm->raise_event( lo_event ).
    ENDIF.
  ENDMETHOD.

4.打开FPM_WB.新建empty application。
