Which Tools Can Be Used for Troubleshooting?

Errors might occur while operating and administrating SAP NetWeaver Gateway Framework. A variety of tools are available to help you analyze the cause of the problem and debug such errors.

Error Log

Use this tool to analyze errors that have occurred and led to a termination of an OData request or notification processing (push channel).

• SAP NetWeaver Gateway hub system: transaction /IWFND/ERROR_LOG.

• SAP Business Suite backend system: transaction /IWBEP/ERROR_LOG.

For more information, see Error Log .

In addition, you can use the Application Log Viewer to check more technical error details.

• SAP NetWeaver Gateway hub system: transaction /IWFND_APPS_LOG.

• SAP Business Suite backend system:: transaction /IWBEP/VIEW_LOG.

For more information, see Application Log Viewer.

Performance Trace

Use this tool to analyze performance problems relating to OData request processing.

• SAP NetWeaver Gateway hub system: transaction /IWFND/TRACES.

For more information, see Performance Trace.

Gateway Client

Use this tool to test your OData service provider without an OData consumer application.

• SAP NetWeaver Gateway hub system: transaction /IWFND/GW_CLIENT.

For more information, see Gateway Client.

Notification Monitor

Use this tool to check and analyze notification processing (push channel) in the SAP Business Suite backend system or SAP NetWeaver Gateway hub system.

• SAP NetWeaver Gateway hub system: transaction /IWFND/NOTIF_MONITOR.

• SAP Business Suite backend system: transaction /IWBEP/NOTIF_MONITOR.

For more information, see Notification Monitor.

You can use the following standard ABAP troubleshooting tools for SAP NetWeaver Gateway:

• Analyze Application Log: transaction SLG1

• CCMS Monitor Sets: transaction RZ20

• ABAP Runtime Error: transaction ST22

• System Trace: transaction ST01

   

You can also use SAP Solution Manager diagnostics to perform an end-2-end trace. For more information, see SAP Note 1435190 (SAP client plug-in) and SAP Note 1041556 (SAP HTTP Plug-In for IE). This is an instrument browser with a plug-in as described in SAP Note 1435190 and it calls SAP NetWeaver Gateway services from a browser. The SAP Solution Manager diagnostics pull standard traces from SAP NetWeaver Gateway.

Before you create a customer service ticket, check the following:

• Ensure OData compliance:

  • Validate test URL against OData specification http://www.odata.org/developers/protocols/overview

  • Test URL by checking a corresponding URL against the OData reference service http://services.odata.org/OData/OData.svc/

• Exclude side-effects caused by metadata cache: see Metadata Cache.

If you are unable to solve the problem yourself using the standard ABAP tools or the supportability tools for SAP NetWeaver Gateway, create a customer service ticket on an SAP NetWeaver Gateway component. For more information about how to create a customer service ticket and to ensure that you include all the relevant context information, see SAP Note 1579681 .
