Mule-com.sap.conn.rfc.exceptions.RfcGetException: Transaction“”是未知的

Question

我正在尝试发送XML，将其转换为BAPI对象，在mule中的转换器中使用XMLto BAPI。我测试了连接，结果成功了。在访问SAP时，我得到了以下错误：

我的配置如下所示：

连接器参考

<sap:connector name="SAP" jcoAsHost="${SAPHost}" jcoUser="${user}" jcoPasswd="${password}" jcoSysnr="${SAPSystemNumber}" jcoClient="${SAPClient}" jcoLang="${loginLanguage}" validateConnections="true" doc:name="SAP"/>
<sap:xml-to-function xmlVersion="2" name="XML_to_SAP_Function__BAPI_" doc:name="XML to SAP Function (BAPI)"/>

SAP出站：

 <sap:outbound-endpoint exchange-pattern="request-response" connector-ref="SAP" type="function" functionName="*******" xmlVersion="2" outputXml="true" responseTimeout="10000" transformer-refs="XML_to_SAP_Function__BAPI_" doc:name="SAP"/>

我刚接触过SAP骡子。请帮助我，可能的原因是什么。

我正在使用的版本是最新版本。

谢谢

Answer 1

启用JCO跟踪，以便找到问题所在

若要在连接器级别启用跟踪，请执行以下步骤：

将属性jcoTrace设置为true，或提供值为1的扩展JCo属性jco.client.trace或jco.server.trace。

在Mule ESB启动时为-Djco.trace_level=N提供一个值。JCo提供从0到10的跟踪级别。跟踪数据量随所选跟踪级别的增加而增加。每个跟踪级别还包含来自较低跟踪级别的所有跟踪数据。有关跟踪数据的详细信息，请参阅下表。如果您使用的是高JCo跟踪级别，其中包含大量JCo调用和传输的内容，请确保有足够的磁盘空间可用。默认值为0。

Answer 2

为了有一些上下文，您正在使用哪种具体的版本的SAP连接器、JCO、Anypoint和Mule运行时？

此外，您能否提供Mule应用程序的完整XML示例，包括正在执行的转换("XML_to_SAP_Function__BAPI_")？
