Hi Hugo,
I'm sorry but I don't quite understand your issue. Are you having trouble consuming a web reference?
If so please send the WSDL so I can take a look.
Cheers,
Tiago Simões
Got it!
Can you call that web service with another application (e.g. .NET)?
If so please send detailed information to support@outsystems.com so they can take a look.
