Multiple Notifications Triggered When Using gs.eventQueueScheduled() in Business Rule

[SREEKANTH_P]

Hi all,

I have a requirement to send two email notifications for Change Requests of type Normal:

When the Implementation Start Date is reached

When the Implementation End Date is reached

I'm using a Business Rule that triggers an event using gs.eventQueueScheduled() at the scheduled time. The logic works as expected, and the notifications are sent at the correct time.

However, the issue is that the notification is being triggered more than once, causing duplicate emails.

Can anyone please suggest why this may be happening and how to ensure the event/notification is triggered only once?

Thanks in advance for your inputs!

Hello @SREEKANTH_P 

Since you're using an 'After Update' Business Rule, is there anything in the system (like a script, Flow, or another Business Rule) that might be updating the record again after it's saved? That could be triggering the rule multiple times and causing duplicate notifications.

@SREEKANTH_P ,

The duplicates are happening because every time your Business Rule fires you call gs.eventQueueScheduled() without first checking whether there’s already an unsent (sysevent.state = ready) event for that same event name, table and record, so as a best practice before scheduling a new one run a GlideRecord query on the sysevent table filtering by state = ready, your event name, table = current.getTableName(), instance = current.sys_id, delete all matching ready events, and then call gs.eventQueueScheduled so you guarantee only one pending event exists at a time, effectively preventing duplicate emails.......

Try updating the condition as 

State [Changes to] Scheduled
