How to copy custom field value to a jira system field - scriptrunner post function

[Bojana Vasic]

Hi,

I need to copy a custom field value to a system field and will use a copy/link issue post function by scriptrunner. How can I copy a custom filed value to a jira system filed "Description" with a simple script? 

Many thanks!

Hi @Raynard Rhodes ,

Will check ... but what I need is vice versa to what is described there, I need a post function script "...to copy a custom field value to a jira system field".

Thanks!
