How to automatically copy field values

[ChangSoo Yoon]

1. I have a field A of the form Date(yyyy-mm-dd)
2. When an issue is created, copy field A value in YYYY-MM format
3. Enter in text field B, in YYYY-MM format

Is it possible?

Ex)
A(DATE Field) : 2023-05-30 ==== when create issue ====> B(text field):2023-05

Hi, @ChangSoo Yoon 

Yes, it's possible. You'll need to use regexp. Something like this:

{{issue.description.replaceAll("(\d{4})\/(\d{1,2})\/(\d{1,2})", "$3/$2/$1")}}
