Hi, @sabined51282667 .   Did you ever get to a resolution to this?   I'm in almost the exact same situation as you (Order is recorded, but Revenue is not), and I get the exact same error message.

@trevorpaulsen  - interested to know which feature that's been added to Adobe Analytics Workspace in the last year or so you are convinced is most under-rated.Maybe one that you think hasn't received the attention it deserves or you think it might be misunderstood. 

What does the immediate export look like (i.e. the one you get if you select the option to get an export while you're doing the import via the browser)? Is there any chance there's a Classification Rule Builder entry that's over-riding what you've done?

@pradeep_07  Did you get any further information on your question? I can't find any useful information about the end-of-life for Data Connectors.
