BAPI的使用说明中文版Word文档下载推荐.docx

1、 INACT like JEST-INACT TXT04 like TJ02T-TXT04 TXT30 likeTJ02T-TXT30 Export parameters RETURN like BAPIRETURN Step1:定义BAPI用到的结构体在此步骤里,BAPI中用到功能模块的表和参数均已在这里定义使用数据类型-结构定义以下结构:结构1:ZBAPI_ORDER_STATUS_IMPORT包含以下字段 ORDERID Order number （Keyfield） 订单号 SPRAS Language 语言结构2:ZBAPISTAT:OBJNR like JEST-OBJNR STA

2、T like J_STAT INACT like J_INACT TXT04 like J_TXT04 TXT30 like J_TXT30 OBJNR like J_OBJNRImportant note:You will have to define a structure for every parameter in the BAPI. You cannot use the same structures used in existing applications because BAPI structures are frozen when BAPIs are released and

3、 then there are restrictions on changing them. 你必须为每个BAPI中的参数定义结构,当BAPI被释放后是限制更改他们的,因为bapi会被冻结,所以你不能在存在的应用中使用同一个结构ZBAPI_ORDER_STATUS_IMPORT 结构1 ZBAPISTAT -结构2 第二步:写入功能模块Important notes: 每个BAPI必须有他们自己的函数组（功能组） 在属性tab里记住选择存取类型是Remote Enabled module,否则功能模块不能通过RFC来invoke它做为一个BAPI来使用 输入/输出参数仅仅能被BY VALUE

4、对于RFC enabled的功能模块 我们在此仅创建了一个BAPI,但你能创建相关的BAPI在同一模块池中,使得他们能共享全局信息功能模块的属性设定输入参数 这里定义功能模块的输入参数为订单输入参数的结构,即是引入结构ZBAPI_ORDER_STATUS_IMPORT做为bapi_order_status_import的参照Export Parameters Code Notes: The subroutine SET_RETURN_MESSAGE is a standard routine used for BAPIs that use the BAPIRETURN structure SE

5、T_RETURN_MESSAGE子程序是在BAPI中标准的子程序用来使用BAPIRETURN 结构 在FORM Z_BAPI_GET_ORDER_SYSTEM_STATUS里有个测试是IF 1=2,如果这测试结果为真,则信息就显示,但是这个条件永远不会为真,所以我们就不可能在BAPI里显示出这个信息,为什么要包含这个的原因是,为信息创建一个参照,因此这时SAP标准控制方法,拷贝公司代码层面的代码GetList BAPI. In form Z_BAPI_GET_ORDER_SYSTEM_STATUS there is a test IF 1 = 2. If the test is true a

6、message is displayed. The condition will obviously never be true, and we will never want to display a message in a BAPI. The reason why it is included is, that it create a reference for the message, so that the WHERE USED functionality can be used for the message. This is the SAP standard way to han
