SAP Business One Web Services Tool v1.1
If you are developing an addon for SAP Business One and you want to use the DI Server, B1WS is the tool you need. B1WS will expose the DI Server functionality as Web Services to provide a better usability. Developers only need to add the web references to the B1WS web services (presented as wsdl files) and use the services with the auto generated .NET object model. Development time is considerably reduced with the use of B1WS!
