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.

We aware of the recently disclosed Apache Log4j2 vulnerability (CVE-2021-44228), although Write-Back is not directly affected by this vulnerability we are actively working on upgrading log4j for the latest version to fix this issue completely. We will let you know as soon as we make available minor versions for Write-Back 3.1 and 3.2 with this fix.

If you are experiencing the extension staying blank on Tableau Server, this is a known issue from Tableau and they already provided a fix for it.

The fix has been applied to Tableau online in January and to Tableau Server in:

Important Notes

We have detected an issue with Tableau Desktop 2021 that will make Write-Back appear to be frozen and it can happen when navigating between datasources and worksheets or simply duplicating a dashboard.

This is affecting all dashboard extensions and Tableau is already aware of this issue.

For the moment, as a workaround, resizing the dashboard should "unfreeze" the extension and make it go back to normal.

We have detected an issue with Tableau Desktop 2020.4.2 which prevents using special characters that are inputted with ALT GR such as '{', '[', ']', '}', therefore this makes it so that to write conditional fields, you have to copy and paste the character from outside of the extension first.

The same issue was found from 2020.2.7 onwards and 2020.3.6 as well.

UPDATE: We had word from Tableau indicating that this is an issue on their side and they are working on it.

Release 3.0 of Write-Back had major enhancements. If you need information about the previous version 2.2 please go to Tableau Write-Back Documentation Home.
