使用Cloud原型在本地调用BAPI时找不到目的地

Question

我遵循正式文件在SAP平台和本地调用BAPI的Cloud原型。Cloud版本为3.35.0。

它在SAP平台上运行良好，提供了RFC目的地，但无法在本地找到目的地。我完成了文档中的所有步骤。

下面是代码片段。

public List<CostCenter> getCostCenters() {
        
        System.setProperty("jco.destinations.dir", "C:\\tools\\SAP\\destinationrfc");
        log.info(System.getProperty("jco.destinations.dir"));
        
        Destination destination = null;
        BapiRequestResult resultGetCostCenters = null;
        try {
            destination = DestinationAccessor.getDestination("s4x011rfc");
            log.info("Get destination successfully.");
            resultGetCostCenters = new BapiRequest("BAPI_COSTCENTER_GETLIST1")
                                       .withExporting("CONTROLLINGAREA", "BAPI0012_GEN-CO_AREA", "0010")
                                       .withTable("COSTCENTERLIST", "BAPI0012_CCLIST").end()
                                       .withTableAsReturn("BAPIRET2")
                                       .execute(destination);
            log.info("Get costcenters successfully.");
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
        
        log.info("Start to get results.");
        //ResultElement re = resultGetCostCenters.get(0);
    
        return resultGetCostCenters.get("COSTCENTERLIST").getAsCollection().asList(CostCenter.class);
    }

我在文件夹"C:\tools\SAP\destinationrfc“中创建了一个rfc目标文件，并在代码中设置了system属性。

​

然后，我用war部署启动了我在Eclipse中的应用程序(Tomcat是集成的)。应用程序成功启动后，我测试了REST以触发BAPI调用，并获得了以下异常。

更新

我对环境变量中创建的目标进行了一些测试。效果很好。除了文档中的配置之外，还应该在环境变量中创建目标。

在环境变量中，描述定义非常简单。只需要目标名称。注意，目标名称应该与在本地dir中创建的代码和jco目标相同。

Answer 1

我们扩展了从本地机器运行BAPI调用的文档。我们添加了一个关于如何维护环境变量部分的destinations，它让SAP找到目标名称。
