Best way to automatically fill a system field based on a custom field

[Eduardo Perez Soto]

I have a custom field called Story points and based on this field, once this field gets a value, I would like to automatically populate the time estimate with a conversion. My question is, what would be the best way to implement this, using listener or behaviors?

Hi @Eduardo Perez Soto ,

I would say the easiest and simplest will be to use Automation or or a post-function, but based on which apps you have.

The post-function has the limitation that it should happen only the stated transition otherwise it will not be caught anywhere else. Automation can bypass that as well as a listener but the latter requires more configuration
