How can I change the value of a custom field via post function

Question

I have a custom field called "Region" with list values (A, B, C for the sake of simplicity). Now I want to achieve this: Whenever I execute a certain transition, e.g. "Delegate to Region A", the value of the field should change to "A".

I'm using Jira Service Management Data Center and would like to use a post function for this. I can select the post function "Update issue field". However, I don't see "Region" in the dialogue. Any ideas?

Probably, I could use automation rules. But I would prefer to use post functions as automation rules would affect all workflows and not only this specific ones. I think, automation rules are a bit error prone.

Any help is greatly appreciated!

Hi Suprija.  Is there a way to set a field as part of a custom script, not using the "set issue fields" function?  Something like ...

{%if condition %}
   issue.fields.customfield_13747 = "123"
{%endif%}

?

Hi @Tim H_ ,

If you've the Jira Misc Workflow Extensions (JMWE) app installed in your Server/DC instance, you can achieve your requirement by following below steps:

* Add JMWE Set issue fields post-function on the desired transition (Ex: Delegate to Region A) of the workflow.
* Select "Region" for "Add field"
* Add the desired value

BTW, I'm from Appfire, the vendor of JMWE app.

You are probably going to need an add-on then for the workflows to get the field to be available. Something like JMWE or ScriptRunner.

If you want to post the automation rule here for review and suggestions on the conditions, feel free.
