I'm new to Tableau and I found something strange is happening to my .twbx workbook.
I use Tableau Desktop. And I created a twbx workbook, using EXTRACT connection to an Access Database.
However, when the file viewers using Tableau Reader to view the file, I always saw a Access Database record locking file created.
I'm not sure why this is happening. As far as I know, the twbx file is already a zip file that includes all the resources for the workbook need to display.
This is happening because you have not saved your credential into database or you have not shared it with people.
So create new twbx file but with database, not with extracted file. and then take extract and save tableau file with Twbx extension.
Then share it with people.
Please let me know if you face any issue.
