Logging and TracingLocate this document in the navigation structure

The user interface add-on for SAP NetWeaver provides OData services through SAP Gateway. SAP Gateway offers extensive logging and tracing capabilities.

Use the SAP Gateway log viewer (transaction /IWFND/ERROR_LOG) to detect errors with SAP Fiori launchpad. You can filter the result list by namespace and service:

Table 1:
Namespace OData Service Description
/UI2/ PAGE_BUILDER_PERS Issues with SAP Fiori launchpad
/UI2/ INTEROP Issues with navigation from launchpad to application or between applications
/UI2/ TRANSPORT, PAGE_BUILDER_CUST, PAGE_BUILDER_CONF Issues with SAP Fiori launchpad designer

For more information about the logging and tracing capabilities of SAP Gateway, see Trace and Log Files in the SAP NetWeaver Gateway Technical Operations Guide.

On the front end, tracing of JavaScript code is done in the respective browser's JavaScript console.
