When attempting to amend a Datasets scheduled refresh and select a data gateway, it is not letting us either select a gateway or change the gateway selected using the radio buttons.
Please ensure you have created the same data source in Manage Gateways section using the same connection information.
Then please go to Dataset Settings, click on the arrow button in Gateway Connections tab, map the data sources within the dataset to the one in gateway. Then you should be able to to select the gateway.
