Custom Schedules in Tableau Prep Conductor | A Step-by-Step Guide | Tableau 2024.2
Tableau 2024.2 finally lets you set custom schedules for Prep flows, including running on the last day of every month.
- Tableau 2024.2 lets you set custom schedules for Prep flows, accessible via the new Schedule button in web authoring or on desktop.
- Custom schedules give more flexibility than fixed options: choose hourly, daily, weekly or monthly cadence, the time, and specific days such as the last day of the month.
- Tableau automatically calculates the last day of the month, which is useful for jobs that must run on that day rather than relying on the 28th as a safe default.
- You can assign a specific output to a task, so different parts of one flow can be scheduled to output at different times.
- An optional email notification can alert someone in the business when the flow has run and a dashboard has been refreshed.
Tableau 2024.2 adds custom schedules for Prep flows, letting you set precise cadences like the last day of every month instead of relying on approximations, plus optional email alerts when a run finishes.
Tim opens an existing Prep flow (used to feed his Tableau Pulse demo dataset) that already has a monthly schedule, then walks through adding a new custom scheduled task from web authoring.
- Open the schedule tab 0:21
From inside a Prep flow, use the new Schedule button in the top right (available in web authoring, and the same route applies on desktop) to jump into that flow's schedule tasks.
- Add a new task 0:44
In the schedule tasks view you can create a new task rather than just relying on the one that's already there.
- Skip link tasks if not needed 1:00
Link tasks let you chain jobs so one runs after another finishes, but if you just want a standalone schedule you can ignore that tab and go straight to defining the schedule.
- Choose cadence, time and days 1:20
Pick hourly, daily, weekly or monthly, then set the time and specific days; for monthly jobs you can select "last day of the month" and Tableau works out the actual date for you, which is more reliable than defaulting to the 28th as a safe stand-in.
- Remember to hit save 1:42
Clicking away from the schedule screen without saving discards your settings, a quirk that's easy to fall into out of habit from elsewhere in the product, so save explicitly before moving on.
- Assign a specific output to a task 2:01
You can target one particular output within a flow for this schedule, which is useful for merging several pieces of work into a single flow and then scheduling each output to run at a different time.
- Add an email notification 2:27
As an optional extra, enter an email address so someone in the business gets notified when the task completes, useful for flagging that a dashboard fed by this flow has just been refreshed.
- Clicking out of the schedule screen without saving silently discards your changes.
- Custom schedules for Prep were introduced in Tableau 2024.2, so this option won't be available on earlier versions.
Reach for this when a Prep flow needs to run on a date that shifts month to month (like the actual last day) rather than a fixed day, or when different outputs in one flow need to run on different timetables.
