Using Custom Field to Create Template for Description Field

[Jonathan]

Hi. I am trying to prefill the description field of an issue with a text template. I understand the native description field is a core field for JIRA so I have created a custom field titled "Description Software Approval" and I have defined the values by adding in the prefilled text I want. When I go to create an issue I now see the core Description field as well as my custom Description field and my text is prefilled. Nice progress but I just want one description field vs my users seeing the core description and the custom description. I am stuck at figuring out how to edit the workflow transitions and post-functions so that the value from my custom description field populates in to my core description field. Based on other posts I've read I need to create a post function to copy the value of my custom description inside my core description field. When I look at available post functions, I see one titled "Copy field values [ScriptRunner]". Is that indeed the post function I should use? I have not yet purchased ScriptRunner so I am also curious if I can accomplish this without the add on.

Thank you for any advice!

I would recommend that you do buy the scriptrunner plugin.
This is a great add-on that expands Jira usage basically to your own imagination.

Scriptrunner has a feature called Behaviors that allows you to do a great many things to system or custom fields on screen load. or field update (like hiding a field if another field is selected, or changing the values in a pulldown based on another selection).
Meaning you don't need a custom description field to populate the Description field with your requirements.
I've done exactly what you are looking for many many times using Behaviors.

I would recommend that you look into this further to satisfy your requirements.

Thanks

Thank you, Craig! I remember we created one before. Now I will be doing it again in one of my projects. The Scroptrunner Behaviour works like a charm.
