SAP保存操作记录CDHDR和CDPOS表

1)     使用sap的标准函数CHANGEDOCUMENT_READ_HEADERS 和CHANGEDOCUMENT_READ_POSITIONS

CALL FUNCTION 'CHANGEDOCUMENT_READ_POSITIONS' "Change document: Read change document items

EXPORTING

*   archive_handle = 0          " sy-tabix      Handle on Open Archive Files

    changenumber =              " cdpos-changenr  Change document number

*   tablekey = SPACE            " cdpos-tabkey  Object class table key

*   tablename = SPACE           " cdpos-tabname  Object class table name

*   tablekey254 = SPACE         " cdpos_uid-tabkey  Table Key for CDPOS in Character 254

*   keyguid = SPACE             " cdpos_uid-keyguid  UUID in Character Format

*   keyguid_str = SPACE         " cdpos_str-keyguid  UUID in Character Format

IMPORTING

    header =                    " cdhdr   Change document header (structure CDHDR)

   et_cdred_str =              " cdred_str_tab  Additional Change Document - Table for STRINGs

* TABLES

*   editpos =                  " cdshw     Table with edited change document items

EDITPOS_WITH_HEADER =               "CDRED  更改文档,显示结构

EXCEPTIONS

NO_POSITION_FOUND = 1       "               No item foun

WRONG_ACCESS_TO_ARCHIVE = 2  "              incorrect access to archive

 

2)使用select语句直接从表中读取。

直接使用SELECT语句读取数据的示例：

*提取信用额度字段修改的抬头信息       select cdhdr~changenr cdhdr~udate cdhdr~utime
        into corresponding fields of table p_cdhdr
        from cdhdr
        where cdhdr~objectclas = 'KLIM' and
          cdhdr~objectid = wa_customerinfo-kunnr.
      if sy-subrc = 0.
*提取信用额度字段修改的字段值         select cdpos~changenr cdpos~value_old cdpos~value_new
          into corresponding fields of table p_cdpos
          from cdpos
            for all entries in p_cdhdr
          where cdpos~objectclas = 'KLIM' and
            cdpos~objectid = wa_customerinfo-kunnr and
            cdpos~changenr = p_cdhdr-changenr and
            cdpos~tabname = 'KNKK' and
            cdpos~fname = 'KLIMK'.
        if sy-subrc = 0.
       endif.
endif.

可以在CHANGEDOCUMENT_READ_HEADERS 中设置中断获得对象类型。

ex.

提取有变动的 Acc. changes
SELECT SINGLE tabkey value_new  INTO (cdpos-tabkey,ikoinh)
      FROM cdpos
      WHERE   objectclas = 'KRED'
        AND objectid = itab-lifnr
        AND changenr = itab-changenr
        AND tabname = 'LFBK'
        AND fname = 'KOINH'.

提取有变动的vendor最新日期

   SELECT MAX( udate ) INTO itab-cndate FROM cdhdr
      WHERE objectclas = 'KRED' AND objectid = itab-lifnr.
