SAP 比较两个内表记录的差异及取元素域值

ᝰ随心ꦿེএ2023-11-16 10:58

一、比较两个内表记录的差异，可以使用FM：CTVB_COMPARE_TABLES来比较两个内表间的差异，有那些纪录是新增的，那些是修改过的和那些是被删除的。

sql 复制代码

CALL FUNCTION 'CTVB_COMPARE_TABLES'
      EXPORTING
        table_old  = old_tab[]
        table_new  = new_tab[]
        key_length = 22
      IMPORTING
        table_del  = del_tab[]
        table_add  = add_tab[]
        table_mod  = mod_tab[].

PS：在传入和传出内表参数时，如果只写内表名，而不加'\[\]'，会产生runtime error

二、取元素域值

sql 复制代码

 PERFORM FRM_GET_DOMVALUE_TEXT USING 'ZMMD_ZFLZQ' <GFS_DATA>-ZFLZQ CHANGING <GFS_DATA>-ZZQTEXT .
    IF <GFS_DATA>-ZXYLX IS NOT INITIAL .
      PERFORM FRM_GET_DOMVALUE_TEXT USING 'ZMMD_ZXYLX' <GFS_DATA>-ZXYLX  CHANGING <GFS_DATA>-ZLXTEXT .
    ENDIF.
    
*&---------------------------------------------------------------------*
*& Form FRM_GET_DOMVALUE_TEXT
*&---------------------------------------------------------------------*
*& text
*&---------------------------------------------------------------------*
*& -->  p1        text
*& <--  p2        text
*&---------------------------------------------------------------------*
    FORM FRM_GET_DOMVALUE_TEXT USING P_DOMNAME
                                  P_VALUE
                         CHANGING P_DOM_TEXT .

  DATA: LV_DOMNAME TYPE DD07L-DOMNAME,
        LV_VALUE   TYPE DD07L-DOMVALUE_L.
  DATA: LS_DD07V TYPE DD07V,
        LV_RC    LIKE SY-SUBRC.

  LV_DOMNAME = P_DOMNAME.
  LV_VALUE   = P_VALUE.
  CALL FUNCTION 'DD_DOMVALUE_TEXT_GET'
    EXPORTING
      DOMNAME  = LV_DOMNAME
      VALUE    = LV_VALUE
*     LANGU    = ' '
*     BYPASS_BUFFER       = ' '
    IMPORTING
      DD07V_WA = LS_DD07V
      RC       = LV_RC.
  IF LV_RC = 0 .
    P_DOM_TEXT = LS_DD07V-DDTEXT .
  ENDIF.
ENDFORM.
