Final answer:
The recommended actions for resolving the error while saving a workbook in Tableau Server
Step-by-step explanation:
The subject of the question is Computers and Technology, specifically related to Tableau Server and its configuration. The error message indicates that the server being used does not allow external database connections.
The recommended action to resolve this error is to:
- Use the data menu to create an extract for the given data sources. This will create a local copy of the data within Tableau, eliminating the need for external database connections.
- Changing server settings may also be an option, if permitted, to allow external database connections. This requires administrative access to the server.
- Clearing cache and trying again could solve the issue if it is caused by temporary data conflicts or corruption.
Restarting Tableau Server might also help, but it should be considered as a last resort if the other options don't work.
