    SAP MM 预留单据的历史修改记录?

    在笔者眼里,SAP系统是一个高度严谨的软件系统。用户在SAP系统里的相关操作,系统都会做记录。用户对于系统的相关单据的增删改,SAP系统都有保留change history,并且可以很方便被人查询这些change history。但是笔者发现,并不是所有单据的修改,SAP系统都提供很好的查询change history的方式,比如Reservation单据。

    如下的预留单ITEM,笔者有将数量由80改成了81,

     

    笔者试图找到该预留单据的change history, 如同查询其它单据修改记录的方式,找遍了MB23事务代码里的诸多菜单,都找不到。

    上网查资料,发现SAP标准系统是不保留预留单据的change history信息的。看来SAP保持增删改的痕迹以方便后续追溯的严谨风格,执行的并不彻底!当然SAP系统对于任何单据的修改都有记录在表CDHDR & CDPOS里,但是标准系统里,这2个表里的数据,对于业务用户,并不能方便的查询。

    SAP NOTE 1927840 供参考。

    1927840 - Change log for reservations

    Symptom

    Create a Purchase Requisition with reference to a reservation and later make changes to delivery date,for example, in transaction ME52N. The field RESB-BDTER is updated with the delivery date changes but no change log is written.

    You would like to record changes made to reservations.

    Reproducing the Issue

    Call a reservation in transaction MB22.

    Make a change to the reservation.

    Save the changes.

    There is no change log.

    Cause

    This is standard SAP system design.

    Resolution

    In enhancement MBCF0007 you find user exit EXIT_SAPMM07R_001.

    This user exit is called directly after the COMMIT WORK statement in MB21/MB22 and contains information related to the old and new item details in table RESB. You could use this user exit to update the reservation changes to a custom table.

    The standard change log table are CDHDR & CDPOS. If you were to use these as part of a custom development to capture reservation changes you would have to pay special attention to performance as these tables are often very large.
