Help with automation in JIRA Cloud

[Erika Reategui]

Hello everyone,

I hope someone can help me with this issue. I’ve spent a lot of time trying to figure it out, so I decided to reach out to the Atlassian Community.

I built an automation to update a custom field on a linked issue in a Discovery Project whenever a custom field on the Discovery Project is updated or edited. My goal is for the same value added to the custom field on the Discovery Project to also be added to the custom field on the linked issue.

I should mention that both custom fields has the same name.

Discovery Product Project

"Quarterly Rank"customfield_11283

Linked Item

"Quartely Rank" customfield_11976

This is how I built the rule

==========================

I am getting the following error on the rule

Field value changed10/22/2025, 13:18:33

BRANCH

Branch rule / related work items10/22/2025, 13:18:33

Edit work item10/22/2025, 13:18:33

We encountered multiple fields with the same name and type:

Quarterly Rank (com.atlassian.jira.plugin.system.customfieldtypes:float)

Issues edited successfully

VIF-7709

Spaces:

DPP. SPP

The error message says that there are multiple fields with the same name, but there aren’t. Even though the automation shows that the issue was edited, the value is not being added to the custom field on the linked item.

Can someone help me figure out how to make this work?

Thank you!

Hi @Erika Reategui 

Are your work items in different projects: the JPD project and another one for the linked item?

If so, please note even though the fields have the same name, they are different in the configurations for those projects.  The rule will need to use a JSON expression to copy the value rather than use the field dropdown list in the Edit Work Item action.

What are the types for your fields?  Knowing that will help the community offer specific suggestions on making the edit.

Kind regards,
Bill
