Set summary automatically when creating a issue

[BZCC IT]

I'm customizing it project that do not need summary, but an serial number is there, but the system requires a summary, so I want to use the post transition function to fill the summary with the "serial" field that I created as an custom field in the create screen.

I'm try to use "Add Post Function To Transition", "Update Issue Field" and find the "summary" is there in the "Issue Field", but do not know how to set the "Field Value" so that the summary can be set with the value of the custom filed "serial"

any advise?

I've search this question but find almost the same suggestion using scriptrunner, just want to know if there's a simpler way to do this.

Thanks.

Atlassian used to have a document on "customising text", but they've deleted it and seem to have removed the content (not just absorbed it into another page), presumably to strongly discourage you from doing this sort of thing.

JIRA uses a language file to generate all the data you see on the front end, and you used to be able to hack that to change things like this.  This approach seems to be changing, which is why I think they've killed off the original page.  The other route that is still open is to use a "translation" and translate Jira's default English into an English suitable for your usage - see https://confluence.atlassian.com/display/JIRA/Translating+JIRA
