第一代sap提供一個空代碼的子過程，在這個子過程中用戶可以添加自己的代碼，控制自己的需求。這類增強(qiáng)都需要修改sap的標(biāo)準(zhǔn)代碼。示例：USEREXIT..inSAPMV45A2、 第二代sap提供的是CUSTOMER-FUNCTION，它是通過SMOD和CMOD完成實(shí)現(xiàn)。參見我的/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提供的第三代的用戶出口就是BADI，他的調(diào)用方式是CALLMETHOD(instance)，(相關(guān)的TCODE是SE18和SE19)，你可以通過EXIT_HANDLER這個單詞查找BADI。另外還有一種出口叫BTE相關(guān)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進(jìn)行SD的用戶增強(qiáng)1、關(guān)于增強(qiáng)的簡單介紹SMOD包含具體的增強(qiáng)，而CMOD是包含一組SMOD編寫的增強(qiáng).Userexits(Functionmoduleexits)是sap提供出口，它的命名規(guī)則如下：EXIT_<programname><3digitsuffix>示例：sd的VA01事務(wù)，對應(yīng)的程序是SAPMV45A，你會在程序里查到(用CALLCUSTOMER-FUNCTION字符串)如下代碼：CALLCUSTOMER-FUNCTION'003'exportingxvbak

選擇一個增強(qiáng)，如：SDVFX001，點(diǎn)擊修改，進(jìn)入sap增強(qiáng)維護(hù)屏幕；2.2、 點(diǎn)擊“組件”按鈕，進(jìn)入組件維護(hù)屏；2.3、 將光標(biāo)移到“功能模塊名”，輸入模塊名，如：EXIT_SAPLV60B_001；2.4、 選擇“代碼修改”按鈕進(jìn)入函數(shù)模塊；2.5、 雙擊函數(shù)模塊的包含單元，進(jìn)入包含單元加入自定義代碼并激活保存；3、 使用CMOD建立增強(qiáng)項目3.1、 輸入自定義的項目名，點(diǎn)擊“創(chuàng)建”；3.2、 進(jìn)入增強(qiáng)項目，選擇“配置增強(qiáng)”，進(jìn)入增強(qiáng)配置屏幕；3.3、 輸入增強(qiáng)名如：SDVFX0013.4、保存，并退出;4、使用CMOD將增強(qiáng)項目激活，便大工告成。如何查找*判斷是否存在相應(yīng)增強(qiáng)的定義(SMOD)selectsinglenamefrommodsapaintomod0-namewherename='PPCO0002'.ifsy-subrc=0.endif.selectsingle*fromtadirintops_tadir_dbwherepgmid

sap程序都會調(diào)用cl_exithandler=>get_instance來判斷對象是否存在，并返回實(shí)例；其實(shí)get_instance就是對上述幾個表和他們的視圖(V_EXT_IMP和V_EXT_ACT)進(jìn)行查詢和搜索。3、 基于這個機(jī)理，我查用ST05來監(jiān)控一個TCODE來跟蹤，然后選擇查找有關(guān)上述幾個表和視圖的操作，就可獲得相關(guān)BADI。4、
