I had the same question earlier this week. I found this resource. https://www.qualtrics.com/support/survey-platform/common-use-cases-rc/pulling-data-into-a-second-survey-longitudinal-surveys/
OK. I just walked through the process with my file. I didn't spend much time planning or making it pretty, so you'll see the raw process I used. I added my email and phone number to the very end in case that's necessary. Video is at https://www.screencast.com/t/2qzuF02pEE
It will be easier for me to show than describe the problem. I'll make a quickie video and post the URL as part of this thread when it's ready. (Because I've been losing a battle with other technology today, I might wait until tomorrow to allow my frustration level to settle a bit.)
Amen! I'm trying to summarize the results of the third administration of a survey. I built the workbook after the first administration (hours and hours). After the second administration, I simply refreshed the extract (a minute or two). I expected to simply refresh the extract after this third administration but I'm hitting this problem of not finding data. I get the same errors on my existing file, but it will connect to the data if I start entirely fresh. Based on your experience, I think I'm going to shift my efforts to making a new connection with my necessary joins and replacing the data source in my existing file. If you don't already know about this, my advice is "Don't rebuild. Replace!" You can find a pretty good description of replacing data source at https://community.tableau.com/thread/127890, but -- I use a slightly different method that doesn't require XML editing. Let me know if you want details. This is SO frustrating!
Same thing happening here!! 'Maddening' is definitely the right word. I've been trying to refresh results for a day or so. Finally dug in to make it work and am ready to pull my hair out. Sometimes I get the error you mentioned ('unable to create extract') and other times it has connected but there is zero data returned.
