We have detected that there is an issue with Tableau Desktop 2020.4.2 which prevents using Write-Back with localhost. We are in touch with Tableau to try and solve this problem. In the mean while please use version 2020.4.1
Tableau is an amazing tool to analyze and explore data but have you ever came across a use case where you would need users to input data? There are many examples such as: forecasting, planning, adding comments or any actionable process. Most of the time you’ll use another tool to input the data which comes with important disadvantages: a separate tool is needed, so you won't be on the Tableau flow anymore, no security and no auditing.
Write-Back, which is a Tableau extension, solves these challenges by allowing you to submit the data directly from your Tableau dashboard and with all the features that make it an enterprise grade extension.
