I just started working with Tableau and is already facing issues when trying to connect to my data.
Hence, it states "An error occurred while communicating with the data source". Details: "Tableau Data Engine Error: 40430: error generating sort key".
I've tried to limit the column length in excel as advised by "error 4 questions - error generating sort key". However, it is still not working. I am using Tableau Desktop professional edition 10.1.3 and is trying to connect to an excel xlsx file.
