业务背景：

在FAGLL03行项目报表中，显示总账科目名称、功能范围名称等。

解决方案：

Se11：Append Structure to faglposx

SE19 实现FAGL_ITEMS_CH_DATA

加入code实现：

METHOD if_ex_fagl_items_ch_data~change_items.

  DATA: wa_items TYPE faglposx,
      zztxt20  TYPE faglposx-zztxt20,"科目名称
      zzktext  TYPE cskt-ktext,"成本中心文本.
      zzfkbtx  TYPE faglposx-zzfkbtx,"功能范围名称
      zzrstgr  TYPE faglposx-u_rstgr,"原因代码
      zzrstgr_t  TYPE faglposx-zzrstgr_t."原因代码名称

  LOOP AT ct_items INTO wa_items.
    "获取科目名称
    SELECT SINGLE txt20 FROM skat
      INTO zztxt20
      WHERE ktopl = '1000'
        AND saknr = wa_items-konto
        AND spras = '1'.
    IF sy-subrc = 0.
      wa_items-zztxt20 = zztxt20.
    ENDIF.

    "获取成本中心名称
    SELECT SINGLE ktext FROM cskt
      INTO zzktext
      WHERE kostl = wa_items-kostl.
    IF sy-subrc = 0.
      wa_items-zzktext  = zzktext.
    ENDIF.

    "获取功能范围名称
    SELECT SINGLE fkbtx FROM tfkbt
      INTO zzfkbtx
      WHERE fkber = wa_items-fkber
        AND spras = '1'.
    IF sy-subrc = 0.
      wa_items-zzfkbtx  = zzfkbtx.
    ENDIF.

    "获取原因代码名称
    IF wa_items-konto(4) EQ  '1001'
      OR  wa_items-konto(4) EQ '1002'
      OR  wa_items-konto(4) EQ '1012'.
      SELECT SINGLE rstgr FROM bseg
        INTO zzrstgr
        WHERE bukrs = wa_items-bukrs
          AND  gjahr = wa_items-gjahr
          AND  belnr = wa_items-belnr
          AND buzei = wa_items-buzei.
      IF sy-subrc = 0.
        SELECT SINGLE txt20 FROM t053s
          INTO zzrstgr_t
          WHERE bukrs = wa_items-bukrs
            AND rstgr = zzrstgr
            AND spras = '1'.
        IF sy-subrc = 0.
          wa_items-zzrstgr_t  = zzrstgr_t.
        ENDIF.
      ENDIF.

    ENDIF.

    MODIFY ct_items FROM wa_items.
  ENDLOOP.

ENDMETHOD.

保存激活。 到此为止，已经可以实现对FAGLL03报表的任意设置，任意TABLE，任意field。
