Use custom field 'Start date' from Epic in automation

[Myrthe van Marissing]

Hi! I'm trying to configure an automation on issues where we calculate the Go Live date of a customer. This should be Start date + 4 weeks. 

This Start Date field is customer made field by ourselves. When scrolling through Jira and the internet, the only option I could find was to use {{issue.startDate.plusDays(30)}}, but unfortunately this isn't working. 

Does anyone know how I can create an automation for new Epics where I can calculate the Go Live date, by adding 4 weeks (or 30 days) to our Start Date custom field?

Hello @Myrthe van Marissing 

Welcome to the community.

Please share screenshot of your current rule, it will help to know your trigger. You *may* have to add a refetch action after your trigger sometimes and that solves the problem.

Another common issue when working with smart values is field names. Hoping this custom Start Date is a date picker field. Can you share a screenshot of the field on the screen so we know what its called.

Cause If field is called Start Date, then you should use {{issue.Start Date.plusDays(30)}} instead of {{issue.startDate.plusDays(30)}}.

And, If you know the customfield value for this field, even better. But most of the times, just using the display name of the field works.

So just using {{issue.Start Date.plusDays(30)}} may solve the problem as well.

BTW, you can also try {{issue.Start Date.plusWeeks(4)}} if thats the window you want.

Hope it helps! Thanks.

Adding to Kalyan's suggestions...

Myrthe, you noted "Start Date field is customer made field by ourselves."  But there is already a built-in field with that name.

If you did indeed add a custom field, why create the duplicate field name as that may cause confusion in Jira resolving to the correct field?

Kind regards,
