1.在表里加上日志记录字段

如下所示，在表里新增一个结构，记录创建和修改日志

1.1 加入日志结构

1.2 在代码中调用记录日志通用函数

在代码中调用以下通用函数记录日志：
FUNCTION zbcfm_fill_log2.
*“----------------------------------------------------------------------
"“本地接口：
*” IMPORTING
*” VALUE(IV_UPDKZ) OPTIONAL
*" CHANGING
*" REFERENCE(CS_DATA)
*"----------------------------------------------------------------------

FIELD-SYMBOLS:<fs_f> TYPE any.
DATA:lv_updkz TYPE c.
DATA:lt_callstack TYPE abap_callstack.
DATA:lv_repid TYPE char100.

"如果判断是自定义程序调用（函数除外)，如果是则取SY-CPROG
"不是则判断是函数调用还是report调用
IF sy-cprog+0(1) = ‘Z’.
lv_repid = sy-cprog.
ELSE.
"获取调用程序名称
CALL FUNCTION ‘SYSTEM_CALLSTACK’
IMPORTING
callstack = lt_callstack.

READ TABLE lt_callstack TRANSPORTING NO FIELDS WITH KEY flag_system = ‘X’ .
IF sy-subrc = 0.
"函数调用
lv_repid = VALUE #( lt_callstack[ 2 ]-blockname OPTIONAL ).
ELSE.
"report调用
lv_repid = VALUE #( lt_callstack[ 2 ]-mainprogram OPTIONAL ).
ENDIF.
ENDIF.

IF lv_repid IS INITIAL.
lv_repid = sy-repid.
ENDIF.

IF iv_updkz IS INITIAL.
ASSIGN COMPONENT ‘CRDAT’ OF STRUCTURE cs_data TO <fs_f>.
IF <fs_f> IS ASSIGNED.
IF <fs_f> = ‘00000000’.
lv_updkz = ‘I’.
ELSE.
lv_updkz = ‘U’.
ENDIF.

ENDIF.

ENDIF.

IF sy-subrc = 0.

ENDIF.

IF sy-subrc = 0.
<fs_f> = sy-uzeit.
ENDIF.

ENDIF.

ENDIF.
ASSIGN COMPONENT ‘LCTIM’ OF STRUCTURE cs_data TO <fs_f>.

ENDFUNCTION.

1.3 在SM30里面记录日志

可参考本人这篇博文，地址：https://blog.csdn.net/HAND_YS/article/details/130338370?spm=1001.2014.3001.5502

1.4 缺点

此种方式只能查询修改与创建日期、时间、账号，无法查询哪些字段被修改。同时数据删除将没有日志。

1.5 优点

简单易用

2.表技术设置-日志数据更改

此种方式是基于表的日志，只要表里任何一个字段有修改，或者整条记录的删除、新增都会有对应的一条完整的记录，而不是多个字段修改多条记录

2.1 RZ10或者RZ11修改系统参数

TCODE：RZ10/RZ11
修改参数
rec/client = 300 （代表指定client要启用日志记录）
rec/client = all （代表所有客户端启用）
rec/client = off (不启用日志)
RZ10需要重启系统才能生效，且永久生效
RZ11当即生效，但是下次重启系统该参数将不会生效

2.2 设置表的属性

注意交付类为C，不能为A

点击技术设置

勾选“日志更改”

2.3 查询日志

无论是通过SM30手工前台维护，还是自定义代码进行增删改，均会记录日志到表DBTABLOG。
使用事务代码SCU3查询日志

日志效果如下

2.4 缺点

记录日志数据量会很大

2.5 优点

相比按照字段级别的日志数据量会少一些。假如修改数据，会有新数据和旧数据的对比。删除数据，也能看到操作记录

3 SCDO文档对象

此种方式是基于字段级别的日志，每个字段修改均会有一条记录

3.1 勾选相应字段-数据元素-更改文档

以下2个字段启用日志

3.2 SCDO创建对象，生成日志函数

事务代码SCDO

输入文本、表名，按照情况勾选表名后的选项，比如“内部表”选项：当勾选上则每次处理多条数据，生成的日志函数里包含CHANGEDOCUMENT_MULTIPLE_CASE子函数。不勾上则处理单条数据，生成的日志函数里包含CHANGEDOCUMENT_SINGLE_CASE的子函数。本例处理单条数据，则不勾选“内部表”



输入函数组名称（不需要事先创建）


此时会出现需要创建的清单，最后点击激活按钮

激活成功，即日志相应的对象已经生成

3.3 调用日志函数

3.3.1 表格维护生成器调用日志函数

以下代码为固定代码（如果SCDO维护时表后面的选项改变了，则需要调整以下代码，一般保持空选项即可），直接复制过去即可。以下代码会引用日志对象的2个INCLUDE文件，调用系统自动生成的FORM记录日志。

3.4 查询日志

使用程序CHANGEDOCU_READ 查看更改日志
日志数据记录表 CDHDR、CDPOS

通过在SM30里面新增、修改、删除数据后，查询日志记录如下：

3.5 缺点

需要建立变更对象，同时在使用处调用日志函数，使用相对麻烦。同时是字段级别的日志，数据量会比较大。

3.6 优点

针对字段级别的日志，比较详细

4.SE16N表数据更改日志

4.1 使用要点

使用SE16N更改表数据时会记录更改日志。日志数据记录表 SE16N_CD_KEY（主表）、SE16N_CD_DATA（存历史数据）

4.2 缺点

SE16N权限较大，不能给普通用户使用，在权限方面需要控制

4.3 优点

简单易用。并且记录了历史数据。按照表级别记录日志。
