Reminder automation

Hi @László Kíra 

Whenever you ask for help with an Automation Rule it will help us to help you if you provide:

1. what type of project is this (e.g., company-managed, team-managed, etc.), 

2. images that show your complete rule.

3. images showing the details of any relevant actions/conditions/branches.

4. images showing the Audit Log details for the rule execution.

5. Explain where the issue is.

These questions are not for not willing to help, but to have community members understand on how automation works.

Hi László,

Please post a screenshot of the rule that you have so far. Also, what is not working with it? 

Hi @László Kíra 

The root problem is the trigger type: a scheduled rule can only run at fixed intervals (hourly at best), so there's no way for it to fire "15 minutes before" a specific date-time - the rule has no concept of counting down to a field value.

What works instead: schedule the rule to run every hour, and make the JQL catch anything whose deadline falls inside the next window, e.g.

"Due date time" > now() AND "Due date time" <= 1h

Every issue gets exactly one reminder comment in the hour before its deadline. The precision is "up to 59 minutes early" rather than exactly 15 minutes - that's the ceiling of what scheduled automation can do. If you genuinely need minute-level precision, that's SLA territory: configure an SLA against the due date and use the "SLA threshold breached" trigger, which does fire at a precise remaining-time mark.

Also check your rule's audit log for "no issues matched" - if the JQL uses a custom date-time field, make sure you're using the exact field name and that the scheduled trigger has the JQL in the trigger itself, not only in a later condition.
