Z database table needs to have field creation/update/deletion tracked

Question

Hi,
I have a Z database table.
I have a program that gets data from an excel file and uploads the content to the Z database table.
I need to track the creation/update/deletion of the records in the Z database table.
The Z database table can also have records changed/updated/deleted manually thru table maintenance. These changes also need to be tracked.
How do I do this?

Hi
For a my z-table (called ZFAGTD01), I created the object for change documents, this is the log after generating it:
Change documents: Display information about generated sources                                                                               
Change doc. object Z_PROAGE_PRV                                                                               
Generation on      23.07.2004 11:51:28                                 
            of     SVIL01                                                                               
Include programs and function modules                                  
Data declaration, TOP...................... FZAGPCDT                   
Consisting of............................. FZAGPCDF                   
and....................................... FZAGPCDV                   
Update function module..................... Z_PROAGE_PRV_WRITE_DOCUMENT
Call update function module................ FZAGPCDC

VZFAGTD01
Just as you see, the system has created the fm and some includes containing all data it needs to call the fm.
So u need only to use those includes, just only u need to consider before calling the fm u need to fill:
- The change flag: usually called UPD_<Z table>;
- Fill the header Y<ZTABLE> of z-table with old data;
- Fill the header X<ZTABLE> of z-table with new data;
- Fill the variables   TCODE, UTIME,  UDATE,  USERNAME,
- Fill the variable OBJECTID with the key of Z-table
For example my object is used in my program in this way:
FORM INSERT_CHANGE_DOCUMENT.
  CHECK FL_CHANGE_DOC = 'X'.
  CHECK SY-SUBRC = 0.
  CONCATENATE XZFAGTD01-MANDT XZFAGTD01-BUKRS XZFAGTD01-GJAHR
                                          XZFAGTD01-BELNR INTO OBJECTID.
  TCODE = SY-TCODE.
  UTIME = SY-UZEIT.
  UDATE = SY-DATUM.
  USERNAME = SY-UNAME.
* Load old data: header
  IF ZFAGTD0K IS INITIAL.
    CLEAR YZFAGTD0K.
  ELSE.
    SELECT SINGLE * INTO YZFAGTD0K
                    FROM ZFAGTD0K WHERE BUKRS   = XZFAGTD01-BUKRS
                                    AND GJAHR   = XZFAGTD01-GJAHR
                                    AND BELNR   = XZFAGTD01-BELNR.
  ENDIF.
* Load old data: items
  SELECT * INTO TABLE YZFAGTD01 FROM ZFAGTD01
                            FOR ALL ENTRIES IN XZFAGTD01
                                   WHERE BUKRS   = XZFAGTD01-BUKRS
                                      AND GJAHR   = XZFAGTD01-GJAHR
                                      AND BELNR   = XZFAGTD01-BELNR
                                      AND POSNR_P = XZFAGTD01-POSNR_P.
  SORT: XZFAGTD01 BY POSNR_P,
        YZFAGTD01 BY POSNR_P.
* Check if heade was changed
  IF YZFAGTD0K <> ZFAGTD0K.
    UPD_ZFAGTD0K = 'U'.
  ELSE.
    CLEAR UPD_ZFAGTD0K.
  ENDIF.
  UPD_ZFAGTD01 = 'U'.
  PERFORM CD_CALL_Z_PROAGE_PRV.
  REFRESH XZFAGTD01.
ENDFORM.                    " INSERT_CHANGE_DOCUMENT
