1、细心整理JCO及BAPI学习小节1BAPI的运用11.1 BAPI概念11.2BAPI相关界面11.3BAPI运用方法52.JCO的运用82.1JCO简介82.2JCO运用82.3JCO开发建议101BAPI的运用1.1 BAPI概念Term/SynonymDefinitionBusiness object BO1. 业务对象，封装了及该对象相关的数据及方法；2. 每个业务对象都必需定义关键字段，用于唯一确定一个特定的业务对象；3. 业务对象中某些通用的方法具有标准的定义格式如getlist；4. 业务对象中定义的方法分为Instancedependent方法及instanceindepend
2、ent两类。Business Object Repository业务对象仓库。Business Application Programming InterfaceBAPI1 访问R3中业务对象及业务过程的标准编程接口。 2 BAPIs 定义了BOR中业务对象的方法。 3 BAPIs 通过RFCenable的功能模块实现。4 用户可以自行开发新的BAPI以满足业务需求。 1.2 BAPI相关界面1事务码BAPI：BAPI Explore2双击Function module，可以阅读实现BAPI的功能模块。3在该界面，可以阅读该BAPI的IMPORT、EXPORT、TABLE参数，以及功能模块的相
3、关文档。4事务码：bwo2：Business Object Browser5选中业务对象Salesorder，可以以面对对象的方式进展阅读。注：其中只有蓝色的方法是有BAPI实现的，红色的方法不供应BAPI实现6BAPI测试工具，点下列图中注释的界面7该界面可以输入测试数据，测试相关的BAPI。1.3 BAPI运用方法在ABAP中调用BAPI的方法及调用Function Module的方法一样。只是要留意BAPI函数没有Exception，调用是否成功是通过参数return返回的。该return参数在不同的BAPI中构造不同，可能是structure，也可能是table，编程时要留意。下面的程
4、序是ABAP中调用BAPI_SALESORDER_CREATEFROMDAT2的例子。留意：1 创立时，订单类性等参数必需运用德语代码2 必需调用BAPI_TRANSACTION_COMMIT完成整个事务。3 某些数据必需用帮助构造负责确定所要更新的数据位完成数据更新。如ORDER_ITEMS_IN和ORDER_ITEMS_INX* Order header:* - Order type: OR Important you must use the german code TA* - Sales org: 1000* - Distrb. chan.: 10* - Division: 00* -
