Hi,
I'm using Jira Product Discovery with a Team managed project.
I have 2 project specific fields:
- Date field "Due Date" e.g. 2026-11-30
- Short text field "Target Quarter" e.g. "2026 Q4"
I'm trying to use automation to set the "Target Quarter" from the "Due Date" by setting the formula to
{{issue.duedate.format("YYYY")}} Q{{#=}}{{issue.duedate.month}}/3{{/=}}.ceil
but it always returns the following error (cf image below):
Edited work item successfully, however some of the set fields aren't available.
Fields ignored: Target Quarter (customfield_10487)

The rule is configured in the following way:

Can anyone help?
Thanks,
