Trigger Accounts in Workday Adaptive Planning
Trigger accounts are used in Workday Adaptive Planning cube sheets to ensure formulas only run where relevant data exists. They act as control mechanisms, guiding the system to calculate values only at valid dimensional intersections, reducing errors, improving performance, and keeping your model tidy. If you’ve ever hit the “must evaluate to zero” error, trigger accounts are often the fix. Additionally, understanding Workday Adaptive Planning trigger accounts is crucial for optimising your planning processes.
What is a Trigger Account?
A Trigger Account is a Cube Sheet account used to signal where data exists in your dimensional structure, ensuring formulas only calculate where valid data intersections are present. Without a trigger, Workday Adaptive Planning throws an error when it can’t determine where to run a formula. Triggers solve the “calculations must evaluate to zero” problem by limiting formula evaluation to seeded intersections.
When to Use Trigger Accounts
Use Trigger Accounts when:
- You’re referencing data from outside the cube sheet
- Your formula causes a “must evaluate to zero” error
- You need to optimise cube performance and avoid blank results
How Trigger Accounts Work
Think of it like conditional post delivery:
- If the “mailbox” exists (i.e. the Trigger Account is populated), deliver the formula.
- If the mailbox doesn’t exist, do nothing and avoid an error.
Example:
iff(isblank(ACCT.Trigger), 0, ACCT.GL_External * 2)
This formula says:
Only run the calculation where the Trigger Account is not blank.
Trigger accounts are a key technique for fixing formula evaluation errors. Learn how to use them step-by-step in our Cube Sheet Formula Errors guide.
Best Practices
| Tip | Recommendation |
|---|---|
| Reuse existing cube accounts | Avoid unnecessary account bloat by leveraging existing cube accounts that already have seeded data. |
| Create standalone trigger if needed | Use a simple static value like 1 to flag valid intersections in your cube sheet. |
| Avoid referencing non-cube data without a trigger | Prevent formula errors by ensuring all cube calculations reference known, seeded intersections. |
| Test with sample data | Before scaling your model, test with sample data to ensure your triggers are firing correctly. |
| Automate population if possible | Use integrations or smart formulas to populate trigger accounts without manual entry. |
