7 Troubleshooting and Error Messages

This chapter explains the limitations and workarounds when connecting to SAP. The following topics are discussed:

• Troubleshooting

• BSE Error Messages

The adapter-specific errors listed in this chapter can arise whether using the adapter with an OracleAS Adapter J2CA or with an OracleAS Adapter Business Services Engine (BSE) configuration.

Troubleshooting

This topic provides troubleshooting information for SAP, separated into four categories:

• Application Explorer

• SAP

• OracleAS Adapter J2CA

• BSE

Note: Log file information that can be relevant in troubleshooting can be found in the following locations: The OracleAS Adapter J2CA trace information can be found under the OracleAS_home\opmn\logs directory. BSE trace information can be found under the OracleAS_home\j2ee\home\applications\ws-app-adapter\ibse\ibselogs directory. The log file for Application Explorer can be found under the OracleAS_home\adapters\application\tools directory.

Application Explorer

To use Application Explorer on Windows for debugging or testing purposes, load the batch script ae.bat, found under:

OracleAS_home\adapters\application\tools

On UNIX, load the shell script ae.sh, found under:

OracleAS_home/adapters/application/tools

SAP

Error	Solution
When executing a request, the following error message appears: AdapterException: java.lang.Exception: Function module CUSTOMER_GETDETAIL2 does NOT exist.	Check the syntax of your input XML document and make sure the name of the Remote Function module is correct, available in SAP, and activated.
When executing a request, the following error message appears: AdapterException: java.lang.Exception: Object type unknown for business object: CUST	Check the syntax of your input XML document and verify that the Business Object type exists in SAP and is correct and activated. Also verify that the name of your document is correct.
When executing a request, the following error message appears: AdapterException: java.lang.Exception: Unable to retrieve BAPI name for: CUSTOMER.DETAIL2	Check the syntax of your input XML document and verify that the name of the BAPI is correct, available in SAP, and activated.
When executing a request, the following error message appears: java.lang.RuntimeException: com.sap.mw.jco.JCO$AbapException: (126) OBJECT_UNKNOWN: Basic type or extension does not exist.

When executing a request, the following error message appears: AdapterException: java.lang.Exception: BapiError/BapiAbort: You are not authorized to display customers.	Verify that your user ID has the correct permissions configured in SAP. Consult your SAP administrator for more information.

Note: Activation is an important SAP concept. If an object does not exist in an activated state, it may appear as present on the system, but is not available for use. This is especially important for IDOCs and SAP Business Objects. Consult your SAP documentation for further information.

OracleAS Adapter J2CA

BSE Error Messages

This topic discusses the different types of errors that can occur when processing Web services through BSE.

General Error Handling in BSE

BSE serves as both a SOAP gateway into the adapter framework and as the engine for some of the adapters. In both design time and runtime, various conditions can cause errors in BSE when Web services that use adapters are running. Some of these conditions and resulting errors are exposed the same way, regardless of the specific adapter; others are exposed differently, based on the adapter being used. This topic explains what you can expect if you encounter some of the more common error conditions on an adapter-specific basis.Usually the SOAP gateway (agent) inside BSE passes a SOAP request message to the adapter required for the Web service. If an error occurs, how it is exposed depends on the adapter and the API or interfaces that the adapter uses. A few scenarios cause the SOAP gateway to generate a SOAP fault. In general, anytime the SOAP agent inside BSE receives an invalid SOAP request, a SOAP fault element is generated in the SOAP response. The SOAP fault element contains fault string and fault code elements. The fault code contains a description of the SOAP agent error.

The following SOAP response document results when BSE receives an invalid SOAP request:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">  
 <SOAP-ENV:Body>
      <SOAP-ENV:Fault>
         <faultcode>SOAP-ENV:Client</faultcode>
         <faultstring>Parameter node is missing</faultstring>
      </SOAP-ENV:Fault>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

In this example, BSE did not receive an element in the SOAP request message that is mandatory for the WSDL for this Web service.

Adapter-Specific Error Handling

When an adapter raises an exception during runtime, the SOAP agent in BSE produces a SOAP fault element in the generated SOAP response. The SOAP fault element contains fault code and fault string elements. The fault string contains the native error description from the adapter target system. Since adapters use the target system interfaces and APIs, whether or not an exception is raised depends on how the target systems interface or API treats the error condition. If a SOAP request message is passed to an adapter by the SOAP agent in BSE and that request is invalid based on the WSDL for that service, the adapter may raise an exception yielding a SOAP fault. While it is almost impossible to anticipate every error condition that an adapter may encounter, the following is a description of how adapters handle common error conditions and how they are then exposed to the Web services consumer application.

OracleAS Adapter for SAP Invalid SOAP Request

If OracleAS Adapter for SAP receives a SOAP request message that does not conform to the WSDL for the Web services being carried out, then the following SOAP response is generated.

<?xml version="1.0" encoding="ISO-8859-1" ?> 
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/">
<SOAP-ENV:Body>

  </SOAP-ENV:Fault>
  </SOAP-ENV:Body>
</SOAP-ENV:Envelope>

Empty Result From SOAP Request

If OracleAS Adapter for SAP carries out an SAP object using input parameters passed in the SOAP request message that do not match records in SAP, then the following SOAP response is generated.

Failure to Connect to SAP

If OracleAS Adapter for SAP cannot connect to SAP when executing a Web service, then the following SOAP response is generated:
