The setup
Create a periodic rule that runs daily and targets high-risk customers (or whatever your EODD population is).
Create an expiring whitelist = set the expiry window to match your EODD frequency (e.g., 365 days for annual EODD).
In your EODD completion rule, automatically add the customer to this whitelist when EODD is completed. This acts as a timestamp where the whitelist entry is valid for 365 days or how many ever days you run your DD. This can be configured in the advanced filters section.
In your periodic rule, the alert condition becomes: high-risk customer AND NOT on the whitelist.
The whitelist entry expiring is what signals that EODD is overdue. Once it expires, the customer falls out of the whitelist and the daily rule catches them on its next run.
Example: Say you complete EODD for a high-risk customer, Acme Corp, on April 1, 2025. Your EODD rule adds Acme Corp to the whitelist with a 365-day expiry.
Every day, the periodic rule scans for high-risk customers not on the whitelist. Acme Corp stays suppressed until April 1, 2026 - when the whitelist entry expires. The next daily run after that date fires an alert: "High-risk customer Acme Corp has not had EODD completed in 365 days.
