第一代sap提供一个空代码的子过程，在这个子过程中用户可以添加自己的代码，控制自己的需求。这类增强都需要修改sap的标准代码。示例：USEREXIT..inSAPMV45A2、 第二代sap提供的是CUSTOMER-FUNCTION，它是通过SMOD和CMOD完成实现。参见我的/CompassButton/archive/2006/08/31/1150258.aspx"/CompassButton/archive/2006/08/31/1150258.aspx"/CompassButton/archive/2006/08/31/1150258.aspx3、 第三代sap提供的第三代的用户出口就是BADI，他的调用方式是CALLMETHOD(instance)，(相关的TCODE是SE18和SE19)，你可以通过EXIT_HANDLER这个单词查找BADI。另外还有一种出口叫BTE相关TCODE:FIBFBusinessTransactionEvents(OpenFI)TheOpenFIenhancementtechniquewasdevelopedintheFinancialAccountingcomponent.OpenFIisbaseduponthefollowingprinciples:Applicationdevelopersmustdefinetheirinterfaceinafunctionmodule,anassignmenttableisreadintheaccompanying(generated)code,andthecustomermodulesassignedarecalleddynamically.Thistechniquedifferentiatesbetweenenhancementsthatareonlyallowedtohaveoneimplementationandenhancementsthatcancallmultipleimplementationsinanysequencedesired.Bothindustryspecificandcountry-specificenhancementsmaybedefined.TheconceptsbehindtheBusinessAdd-InsenhancementtechniqueandOpenFIarebasicallythesame.However,thetwoenhancementtechniquesdodifferfromeachotherinthefollowingpoints:OpenFIcanonlybeusedtomakeprogramenhancements,thatis,youcanonlyenhancesourcecodeusingOpenFI.YoucannotenhanceuserinterfaceelementswithOpenFIlikeyoucanwithBusinessAddIns.OpenFIassumesthatenhancementwillonlytakeplaceonthreelevels(SAP-partners-customers),whereaswithBusinessAdd-Insyoucancreateandimplementenhancementsinasmanysoftwarelayersasyoulike.OpenFIusesfunctionmodulesforprogramenhancements.WithBusinessAdd-Ins,ABAPObjectsisusedtoenhanceprograms./CompassButton/archive/2006/08/31/1150258.aspx"/CompassButton/archive/2006/08/31/1150258.aspx"如何使用SMOD和CMOD进行SD的用户增强1、关于增强的简单介绍SMOD包含具体的增强，而CMOD是包含一组SMOD编写的增强.Userexits(Functionmoduleexits)是sap提供出口，它的命名规则如下：EXIT_<programname><3digitsuffix>示例：sd的VA01事务，对应的程序是SAPMV45A，你会在程序里查到(用CALLCUSTOMER-FUNCTION字符串)如下代码：CALLCUSTOMER-FUNCTION'003'exportingxvbak = vbakxvbuk = vbukxkomk = tkomkimportinglvf_subrc=lvf_subrctablesxvbfa=xvbfaxvbap=xvbapxvbup=xvbup.则exitcallsfunctionmodule的名称就是：EXIT_SAPMV45A_0032、 先试用SMOD建立一个SAP增强2.1、 选择一个增强，如：SDVFX001，点击修改，进入sap增强维护屏幕；2.2、 点击“组件”按钮，进入组件维护屏；2.3、 将光标移到“功能模块名”，输入模块名，如：EXIT_SAPLV60B_001；2.4、 选择“代码修改”按钮进入函数模块；2.5、 双击函数模块的包含单元，进入包含单元加入自定义代码并激活保存；3、 使用CMOD建立增强项目3.1、 输入自定义的项目名，点击“创建”；3.2、 进入增强项目，选择“配置增强”，进入增强配置屏幕；3.3、 输入增强名如：SDVFX0013.4、保存，并退出;4、使用CMOD将增强项目激活，便大工告成。如何查找*判断是否存在相应增强的定义(SMOD)selectsinglenamefrommodsapaintomod0-namewherename='PPCO0002'.ifsy-subrc=0.endif.selectsingle*fromtadirintops_tadir_dbwherepgmid

sap程序都会调用cl_exithandler=>get_instance来判断对象是否存在，并返回实例；其实get_instance就是对上述几个表和他们的视图(V_EXT_IMP和V_EXT_ACT)进行查询和搜索。3、 基于这个机理，我查用ST05来监控一个TCODE来跟踪，然后选择查找有关上述几个表和视图的操作，就可获得相关BADI。4、 se18查找接口，se19实现接口就可以实现用户增强。示例：用LE_SHP_DELIVERY_PROC控制跨月CancelMETHODIFEXLESHPDELIVERYPROC~CHANGEDELIVERYHEADER.
