Trying to refresh a dataset from 3 different sources - two are databases within the same server and then one additional server. All have been set up with the gateway I'm using. I haven't seen the...
I identified the source of the error - I appended two tables from different data sources, and once I'd removed the step which appended the tables the refresh was able to go ahead.
