How do I add a customer field value?

[Eric.LA_Chen]

Hi everyone,

I want to create two customer field "effect day" & "expired day"

and "expired day" = "effect day" + 90days.

Can it auto fill in the "expired day" when I create the ticket?

I knew which configuration in workflow -> funciton -> update customer field...

But I do not know what value I should fill it...

Hello,

You can not do it out of the box. You would need a plugin for it. 

For example you could use the Power Scripts add-on:

https://marketplace.atlassian.com/apps/43318/power-scripts-jira-script-automation?hosting=cloud&tab=overview

You could create a post function with a code like this:

#{expired day} =#{effect day} + "90d"; 

 You can read more about post functions here:

Hi, @Eric.LA_Chen!

Another way is to use this add-on:

Jira Misc Custom Fields

You can easily configure so-called "Calculated Date/Time Field".
