Interesting... I haven't seen this behavior before. How were you "running" a report? Extract refresh? Filtering a view?
Also, your workbook isn't terribly useful, as we don't have any of the data unless you save it as a packaged workbook (.twbx). All we can really do now is look at the XML for the calculations, which is only cursorily interesting. I am assuming if you refresh these extracts you just get more of the same as far as the "Extract" tables and calculations go?
It seems that your extract is corrupted and it needs to be created again
1.- uncheck Use Extract: menu Data > your data source name > click on Use Extract
2.- create a new extract: menu Data > your data source name > Extract Data...
Almost sure re-creating your extract will solve the problem.
Yup, remove/delete the extract and re-create it. This should fix this issue, I've seen it time and again!
According to Tableau, the cause is:
The workbook was saved immediately after creating new calculated fields. Then the extract was refreshed, but the workbook was not saved again.
However, I've experienced these calculated field errors when the above was NOT the case so who knows.
I appreciate the suggestions but none have reversed the issue. I would package the workbook but I'm not sure how to do that without exposing sensitive customer data. I'm going to duplicate the workbook, delete the unknown calculations and attempt to recreate from memory.
Again, thanks for the suggestions. If there's a way to package the workbook without exposing customer data I'd be happy to package/upload so the issue can be examined further.
Thanks for finding a related official reason response from Tableau, unfortunately this issue fell under the 'who knows' category!
I would love to upload the packaged workbook but not sure how I can do so without exposing sensitive data...
There is some really good information on how to dummy down data in Tableau in this thread:
There are also a couple of ideas on the forum related to more sample data and randomzing sensitive data.
