模拟VL02N交货单批次拆分

昨天听到一个好玩的需求，自开发交货单批次拆分的界面和实现批次拆分。

批次拆分的函数就不提了，这里来说说自开发程序怎么模拟出批次拆分的那种样子。、

效果图：

1，首先定义一个交货行项目表和拆分出来的批次表：

REPORT zvl02n.

TYPES:BEGIN OF ty_item,
        vbeln   TYPE vbeln_vl, "Delivery
        posnr   TYPE posnr_vl, "Delivery Item
        matnr   TYPE matnr, "Material Number
        charg   TYPE charg_d, "Batch Number
        icon    TYPE icon_d, "
        hi_item TYPE posnr_vl, "
      END OF ty_item.

DATA:gt_item  TYPE TABLE OF ty_item,"交货主行
     gt_fitem TYPE TABLE OF ty_item,"交货拆分行
     gw_item  LIKE LINE OF gt_item,
     ls_item  LIKE LINE OF gt_item,
     gv_field TYPE string,"光标列
     gv_line  TYPE i,"光标行
     ok_code  TYPE sy-ucomm.
*&SPWIZARD: DECLARATION OF TABLECONTROL 'TC_9000' ITSELF
CONTROLS: tc_9000 TYPE TABLEVIEW USING SCREEN 9000.

*&SPWIZARD: LINES OF TABLECONTROL 'TC_9000'
DATA:     g_tc_9000_lines  LIKE sy-loopc.

INITIALIZATION.
  "初始化内表
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '10'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '20'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '30'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '40'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '50'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '60'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '70'.
  gw_item-matnr = 'A1'.
  gw_item-icon = '@3S@'.
  APPEND gw_item TO gt_item.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900001'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '10'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900002'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '10'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.

  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900001'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '20'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900002'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '20'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.

  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900001'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '70'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.
  gw_item-vbeln = '1000000000'.
  gw_item-posnr = '900002'.
  gw_item-matnr = 'A1'.
  gw_item-hi_item = '70'.
  gw_item-icon = ''.
  APPEND gw_item TO gt_fitem.

START-OF-SELECTION.
  CALL SCREEN 9000.

其中添加了7个主行项目，10，20，70分别加了2个次行项目

2，PAI开头获取光标行，这里获取的行号存到全局变量里，为了后面折叠展开事件使用

MODULE get_field INPUT.

  GET CURSOR FIELD gv_field
             LINE  gv_line.
  IF ( gv_line + tc_9000-top_line - 1 ) > tc_9000-lines.
    gv_line = tc_9000-lines.
  ELSE.
    gv_line = gv_line + tc_9000-top_line - 1.
  ENDIF.
ENDMODULE.

3，根据点击的按钮图标添加次行

FORM show_fitem .
  DATA:lv_index TYPE i.
  lv_index = gv_line.
  READ TABLE gt_item INTO gw_item INDEX lv_index.
  IF sy-subrc = 0.
    IF gw_item-icon = '@3S@'.
      gw_item-icon = '@3T@'.
      LOOP AT gt_fitem INTO ls_item WHERE hi_item = gw_item-posnr.
        lv_index = lv_index + 1.
        INSERT ls_item INTO gt_item INDEX lv_index.
      ENDLOOP.
    ELSEIF gw_item-icon = '@3T@'.
      gw_item-icon = '@3S@'.
      DELETE gt_item WHERE hi_item = gw_item-posnr.
    ENDIF.
    MODIFY gt_item FROM gw_item INDEX gv_line TRANSPORTING icon.
  ENDIF.

ENDFORM.

最后说明下，TC里怎么把文本转成ICON

1,取消输入：

2，右键TC里的列转换BUTTON

并添加事件FOD

MODULE user_command_9000 INPUT.
  CASE ok_code.
    WHEN 'BACK'.
      LEAVE TO SCREEN 0.
    WHEN 'EXIT'.
      LEAVE PROGRAM.
    WHEN 'FOD'.
      PERFORM show_fitem.
    WHEN OTHERS.
  ENDCASE.
ENDMODULE.
