can you put the screenshot of the same? can share the sample data or the actual workbook with just 10 rows of data?
Unfortunately, I could not save the workbook. I have now joined data prior to import into Tableau, and no problems, so it was something to do with the join...
Thanks for letting us know Carlton, I have marked your answer correct, as you solved your own issue.

Would you be willing to file a support case? I'd love to get to the bottom of this.
Few clarifying questions though:
- What version are you using? (9.x.x?)
- Do you have headers in all your sheets? Does Tableau recognize them properly?
I've seen this error when column name is too wide and Tableau does not handle it right. Looks like in your case it is "There is something for every student regardless of income level, race, ability, special needs, religion, gender or sexual orien1", no?
Could you try auto-generating column headers for that sheet?
I'm using 9.3.4. Yes, I have headers in all sheets, but there are a number of column names that are quite long. I've noticed Tableau truncates them. Any idea on why this causes a problem?
Tableau's Data Engine imposes column size limit (128 characters) and, looks like, we have a bug around this in certain cases.
In your particular case I believe it is multiple columns in different tables that have the same first 128 characters.
How does your join look like? Is there a self-join? Union?
Could you make beginnings of your long headers unique and try again?
Good to know. I've already resolved the issue by joining data outside Tableau before import, but for future reference will make sure headers are short and unique
I received this same error and found that when I removed non ANCII characters (like ™ and ®) from my data, it would run correctly.
