Mule-com.sap.conn.rfc.exceptions.RfcGetException:Transaction"&引用；未知

我正在尝试使用mule中提供的transformer中的XMLto BAPI将XML转换为BAPI对象。我测试了连接，结果成功了。点击SAP时，我发现以下错误：

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"/>

我是SAP mule的新手。请告诉我可能的原因

我使用的版本是最新的

谢谢

启用JCO跟踪，以便您可以找到问题所在

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，或提供扩展JCo属性JCo.client.trace或JCo.server.trace的值为1

---

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，请参见下表。如果您使用的是高JCo跟踪级别，包含大量JCo调用和传输的内容，请确保有足够的可用磁盘空间。默认值为0。

为了获得一些上下文，您正在使用哪些具体版本的SAP connector、JCO库、Anypoint Studio和Mule Runtime

---

另外，您能否提供Mule应用程序的完整XML示例，包括您正在执行的转换（“XML_到SAP_函数_u到BAPI”）？

请配置Mule和SAP连接器版本。使用哪种RFC调用？是TRfc还是SRfc@SatheeshKumar是sRFC.Balwnat您解决了这个问题吗？？？@SatheeshKumar尚未解决。请配置Mule和SAP连接器版本。使用了哪种RFC调用？是TRfc还是SRfc@SatheeshKumar这是sRFC。Balwnat你解决了这个问题吗？？？@SatheeshKumar还没有。
