To whom it may concern,
I am a Tableau certified and software developer based in Dublin. I’ve been working with Tableau software since version 7 and with software development for more than 10 years.
You can use an ‘User filter’ on Tableau to give and restrict access on row level, according to the user. I main issue in this case é that every time that you have a new user you must change the report manually to grant access.
One way to solve this is create a table on your database to save the users and respective group that hi belongs, and create a view to provide the data to Tableau with the group access; so Tableau will filter the group. In this scenario you just need to update this table.
