When scheduling a task, such as refreshing an extract, the task might not run as scheduled. Manually running the task or refreshing the extract can be done by using Run As User.


Tableau Server


  1. Ensure that the Tableau Server Run As User has Modify, Read and Execute permissions for the following folders: 
    • C:\ProgramData\Tableau 
    • C:\Program Files\Tableau 
  2. Verify that the Run As User has Log on as a Service permission in the Local Security Policy.


The Tableau Server Run As User has insufficient permissions to start the schedule.
