用户出口总结

1、7月27日屏幕增强用户出口-migo创建程序，及其屏幕。2.找到badi的PBO程序。MB_MIGO_BADI - PBO_DETAILE_CPROG = ZTESTZW03.E_DYNNR = 1020.E_HEADING = ztest01.则程ZTESTZW03屏幕1020则被引用到migo的屏幕上。用户出口的总结。一.用户出口的类型1、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. in SAPMV45A2、第二代sap提供的是CUSTOMER-FUNCTION，它是通过SMOD和

2、CMOD完成实现。3、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CALL METHOD (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: FIBFBusiness Transaction Events (Open FI)二，用户出口比较。第一代用户出口是form出口 如FORM USEREXIT_FIELD_MODIFICATION.CASE SCREEN-GROUP3.WHEN 900.IF VBAK-VBTYP NE A.SCREEN-ACTIVE = 0

3、.ENDIF.ENDCASE.CASE SCREEN-NAME.WHEN VBAK-VBELN.SCREEN-ACTIVE = 0.ENDCASE.ENDFORM.找法省略。SD的用户出口和定价的用户出口等多采用这种方式。第二代用户出口多是call customer-function 001这种方式实现的。是通过smod和cmod来实现的，Here are a couple of hints:If you have a user exit function module: EXIT_SAPLEINM_014Fire up SE37 to get the development class ME

4、Fire up transaction CMOD and go to menu option Utilities - SAP EnhancementsEnter the development class ME and execute. This will list all the enhancements available in that development class. Double click at leisureFor those wanting a more scientific method:SE16 with table MODSAP - Enter the functio

5、n module in MEMBER and execute (e.g.EXIT_SAPLEINM_014)NAME is the EnhancementTo find the project that the enhancement is in:SE16 with table MODACT - Enter the enhancement in MEMBER and execute (e.g.MM06E001)NAME is the Project to use in CMOD参考其他资料。第三代用户出口 BADIbadi对象的信息存储在SXS_INTER, SXC_EXIT, SXC_CLA

6、SS和SXC_ATTR这四个表中(参见 SECE 包)；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。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。se18查找接口，se19实现接口就可以实现用户增强。补充7.00版后badi的几个处理变化以前的 CL_EXITHANDLER=GET_PROG_AND_DYNP_FOR_SUBSCR 被 CL_ENH

7、_BADI_RUNTIME_FUNCTIONS = GET_PROG_AND_DYNP_FOR_SUBSCR 代替.以前的PUT_DATA_TO_SCREEN和GET_DATA_FROM_SCREEN不在需要。用户可以创建 自己的数据传输函数，通过CALL BADI来调用.用户也不需要调用 CL_EXITHANDLER=SET_INSTANCE_FOR_SUBSCREENS 和 CL_EXITHANDLER=GET_INSTANCE_FOR_SUBSCREENS 函数.sample : This isan example toshow - howto achieve post-processi

8、ng follow-on processing functionality using BADIs Business Add-inn or user-exits.Find the relevant BADI using transaction SE18. In this case BADI ME_PURCHDOC_POSTED is used.Further, implement the BADI using transaction SE19.In Attributes section of BADI, define a STATIC attribute as PO_NUMBER. Stati

9、c means the attribute will keep its value between the calls. This will be checked to ensure that same PO will not be processed twice. Also these kind of user-exits and BADIs might get called recursively and get caught into an infinite loop, if not coded properly. Rememeber that this BADI is at the t

10、ime of PO save and then you are again trying to change & save the Purchase Order from within the BADI.BAPI to change Purchase Order BAPI_PO_CHANGE will be called IN BACKGROUND TASK to ensure that it will be called when COMMIT WORK is encountered.Dont forget to activate the BADI implementation in SE1

11、9.也可以再后台配置的地方找用户出口。如spro物料管理-采购-采购业务附加等。BTEIMG Menu Path: Financial Accounting Financial Accounting Global Settings Use Business Transaction Events Environment Infosystem (Processes).Find the correct Business Event.
