How To Fix W3_TOOL016 - Browser started

SAP Error Message - Details

• Message type: E = Error

• Message class: W3_TOOL - ITS: Maintenance Messages

• Message number: 016

• Message text: Browser started

What causes this issue?

The Web Browser defined in the system as the default browser was started
to test the URL necessary for the service.

System Response

The system launches a browser window and starts the service.

How to fix this error?

In this window, the system either starts the service directly or
requests any missing data (not set up with the service). If an error
message such as 'Host not reached' appears in the window, the automatic
URL generation in the current SAP system is not working because no ITS
server with a norm-conforming name is logged on to the system.
In this case, you can change your user settings in the Object Navigator
(Utilities -> Settings, "ITS" page) to set the ITS that should be used.
You can also use this, for example, if you want to test a service on a
particular Internet Transaction Server.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
