此BAPI是从JEST读取生产订单系统状态和从表TJ02T中读取文本状态

ZBAPISTATUS（功能组）
Functionmodule:
Z_BAPI_GET_ORDER_STATUS（功能模块）

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
∙ORDERIDOrdernumber（Keyfield）订单号
∙SPRASLanguage语言
∙ExcludeInactive-Checkbox-Excludeinactivestatus
结构2:
ZBAPISTAT:
OBJNRlikeJEST-OBJNR
∙STATlikeJ_STAT
∙INACTlikeJ_INACT
∙TXT04likeJ_TXT04
∙TXT30likeJ_TXT30
∙OBJNRlikeJ_OBJNR
Importantnote:
YouwillhavetodefineastructureforeveryparameterintheBAPI.YoucannotusethesamestructuresusedinexistingapplicationsbecauseBAPIstructuresarefrozenwhenBAPIsarereleasedandthentherearerestrictionsonchangingthem.
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
Importantnotes:
∙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RemoteEnabledmodule,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BYVALUE对于RFCenabled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

Notes:
∙ThesubroutineSET_RETURN_MESSAGEisastandardroutineusedforBAPIsthatusetheBAPIRETURNstructure
∙SET_RETURN_MESSAGE子程序是在BAPI中标准的子程序用来使用BAPIRETURN结构
∙在FORMZ_BAPI_GET_ORDER_SYSTEM_STATUS里有个测试是IF1=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GetListBAPI.
