Cause

Additional Information

Regarding Non-Unique key, “unique” means the source database must have a uniqueness constraint for the column. If it doesn’t, then the extract may be impacted, regardless of whether every row is unique or not.

The window of time in which incremental refreshes were affected on Tableau Cloud, was from the time that the pod was upgraded to version 2023.1 until 5:45 PM UTC on March 21, 2023. Content affected during this window must use the options from the resolution section to address the issue.
