Using epic link to automatically populate a custom field

[Zach Lane]

Is it possible to use the Epic link to automatically a fill a custom field while creating related issues? I'm trying to make it so a charge code for time recording towards specific efforts is automatically filled in based on the epic.

Thanks.

With plugins for sure.

You might want to take a look at these to help you out:

JSU Automation Suite for Jira Workflows (paid)

 - if you are only looking at the 'Create' event, then you should be able to set appropriate post-functions via the JSU functions

Automation for Jira - Server Lite (free and paid, 2 versions)

 - allows you to set up when, conditions, what and where, given some advanced smart value usage this should be possible to set up, either on Create or during the issue lifecycles

ScriptRunner for Jira (paid)

 - mentioning this as the Swiss knife of plugins, it contains most anything that you might need but you would be needing to script it with Groovy

 - either as a custom scripted post-function in workflows

 - or as a scripted listener that will hang on to when you do such an update, and then executing custom code to do what you need

There are plenty of similar plugins that would be able to get this job done, so just mentioning the major / more common players I have a good experience with that you are more likely to find online posts for.
