Activating the web service
The service is administrated using the sicf transaction.

Confirming by clicking the Execute button opens a section with the existing hosts and/or services.

The service can be activated or deactivated in the context menu of the wsdl11 entry that can be found under the path sap => bc => soap => wsdl11. The service sap => bc => soap => rfc must also be activated.

The web service can be reached with the URL http://<sapserver>/sap/bc/soap/wsdl11?sap-client=<Client>.
