Hi,
I have just debugged an error with a colleague of mine where we are getting the error...
They were outputting from a yxdb to a TDE.
On further invesitgation we identified that at a field name with 127 characters, the data outputted fine.
At 128 characters we received the following error:
' Output Data (3) SimpleDatabase::SelectMetadataName: expected found=1, actual found=0 (fk=7 name="aaaaaaaabbbcccccccccccccccccccccccccccccccccccccccbccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccccc" nameTable="COLUMNS")'
And from 129 characters onwards we get the 'comun name too long error'.
I've tested on a number of different outputs and this only appears to affects TDE's.
I then decided to create a datasource in tableau with 129 characters and created an extract, everything works fine.
Is this a bug on alteryx's end? or possibly a limitation of Tableaus api?
Thanks
Ben

That error message is coming directly from the Tableau API. We are passing the full name to the TableauDefinition, and when the "Extract" is created it is throwing that error. This is a limitation of the Tableau API. I just checked the latest version 10.0 and it has the same limitation.
Thank you
