使用SAP Cloud SDK 3.0版从Java调用BAPI

debugcn 发表于 Dev

我目前在POC上工作，我需要使用Java从云应用程序在S / 4HANA内部部署中调用BAPI。为此，我正在使用SAP Cloud SDK。

对于初始设置，我遵循以下步骤：https : //developers.sap.com/tutorials/s4sdk-setup.html

我正在尝试BAPI_COSTCENTER_GETLIST1从我的申请中致电。这是代码片段：

final BapiRequestResult resultGetCostCenters = new BapiRequest("BAPI_COSTCENTER_GETLIST1")
 .withExporting("CONTROLLINGAREA", "BAPI0012_GEN-CO_AREA", "0001")
 .withTable("COSTCENTERLIST", "BAPI0012_CCLIST").end()
 .withTableAsReturn("BAPIRET2")
 .execute(destination);

这里是destination变量的声明：

Map<String, String> destinationProps = new HashMap<String, String>();
// Added a sample destination name. Solved NoSuchElementException error. 
destinationProps.put("Name", "SampleDestination");
destinationProps.put("URL", "<system_url>");
destinationProps.put("Type", "HTTP");
destinationProps.put("Password", "<system_password>");
destinationProps.put("Authentication", "BasicAuthentication");
destinationProps.put("User", "<system_user>");

final Destination destination= new DefaultDestination(destinationProps);

但是从execute()抛出的一个例外说java.util.NoSuchElementException: No value present。这是完整的堆栈跟踪

我认为我缺少一些非常基本的东西。也许我做错了。我找不到有关此主题的任何有据可查的教程。所以，请纠正我哪里出问题了。

提前致谢。
