Add issue key from trigger issue to a custom text field in another issue but not overwrite

[Katy Rupp]

When an issuetype in a specific project is created we want that issue's key to be added to a list of issues in a custom text field. We don't want to overwrite the field but ADD this key to the list of keys in this field. 

I see you can append with JSON but it's not a static value it needs to be dynamic to pull the trigger issue key. Any assistance greatly appreciated.

Hi @Katy Rupp -- Welcome to the Atlassian Community!

You could add the value after the current value.

For example, let's assume you wanted to add the trigger issue's key to the end of a description field being edited.  That would look like this:

{{issue.description}}

{{triggerIssue.key}}

If this does not help, please post an image of your complete rule, an image of the Edit Issue action, and an image of the audit log details showing the rule execution.  Those will provide context for the community to help.

Kind regards,
Bill

Hi @Katy Rupp 

to read a current value (or several) from a custom field and then append a new one without deleting the old I use this:

https://support.atlassian.com/cloud-automation/docs/jira-smart-values-issues/

Go to Field change

• {fieldChange.fromString}} - Returns the previous value as displayed.

• {fieldChange.toString}} - Returns the new value as displayed.

I've used an if/else block to cover several conditions, but this can help you:

Conditions

{{fieldChange.fromString}} does not equal Empty

 And

{{issue.customfield_10174}} equals Empty

then edit issue

{{fieldChange.fromString}}, {{fieldChange.toString}}

 Hope that helps!
