*SMOD包含具体的增强，而CMOD是包含一组SMOD编写的增强.

*sap增强存在MODSAP表内
*MODTYP 类型:
*E : 功能退出
*S : 屏幕
*T : 表
*C : GUI代码

*增强步骤：
*1、先用SMOD建立一个SAP增强
*1.1、选择一个增强，如：IEQM0003，点击查看；
*1.2、点击"组件"按钮；
*1.3、双击模块名，如：EXIT_SAPMIEQ0_001；
*1.4、双击函数模块的include单元，进入include单元加入自定义代码并激活保存；
*
*2、使用CMOD建立增强项目
*2.1、输入自定义的项目名，如：ZIEQM0003，点击"创建"；
*2.2、进入增强项目，选择"配置增强"，进入增强配置屏幕；
*2.3、输入增强名如：IEQM0003
*2.4、保存，并退出；
*
*3、使用CMOD将增强项目激活，便大工告成。

*-- 判断是否存在相应增强的定义(SMOD) --*
tables: mod0, tadir,modsap.
select single name from modsapa into mod0-name where name = 'PPCO0002'.
*或：
select single * from tadir
  where pgmid     = 'R3TR'
    and object    = 'SMOD'
    and obj_name  = 'PPCO0002'.

*-- 判断是否存在相应增强项目的实现(CMOD) --*
select single name from modattr into mod0-name where name = 'PPCO0002'.

*if sy-subrc = 0.
*  write 'ok'.
*endif.

*-- 提取增强的定义的组件 (可以用此反查增强定义) --*
select * from modsap where name = 'F180A001'.
endselect.

*-- 判断该增强是否移植到BADI实现,不懂。。 --*
*Enhancement & has already been migrated in Business Add-In definition
data: migrated like modsapa-migrated,
      exit_name like modsapa-badi_def.
select single migrated badi_def into (migrated, exit_name) from modsapa where name = 'MBCF0002'.
if sy-subrc = 0 .
endif.

*-- 获得function的信息 --*
tables: tftit.
select single * from tftit where spras = '1' and funcname = 'EXIT_SAPLCORE_001'.

*值得学习的函数
*获取增强组件的参见函数MOD_SAP_MEMBER_TEXT
*MOD_KUN_ACTIVATE(会操作相关报表)
