Specifying Port when connecting to SAP BW Server

Hello everyone,

we are struggling with setting up a gateway connection to our SAP BW Application Server.

From PBI Desktop everything works fine but we are not able to set up the connection in the gateway.

We get an error "Timeout expired. The timeout period elapsed prior to completion of the operation." which, according to my gateway admin, is a hint that the wrong port is being requested.

So here's my question: how can I specify which port to use when setting up the connection to the SAP BW Server in PBI Desktop?

Thanks very much in advance for any helpful feedback that you can give!

Best regards,

Paul
