Changing the Summary on an Epic to make changes to all child Summary fields.

[Dan Spearing]

Epic Summary = "Part Number"

Child 1 Summary = "Part Number - Start" 

Child 2 Summary = "Part Number - Do Stuff" 

Child 3 Summary = "Part Number - End" 

Trying to get an automation to change part of the child Summary when the Epic Summary changes. For example:

Change the Epic Summary from "Part Number" to "12345-678" would produce:

Epic Summary = "12345-678"

Child 1 Summary = "12345-678 - Start" 

Child 2 Summary = "12345-678 - Do Stuff" 

Child 3 Summary = "12345-678 - End" 

Here is the Automation and error

I've tried multiple combinations of smart values but I must be missing something simple.

Thanks in advance!

Hi @Dan Spearing 

There are two problems with your smart value expression:

• varSource is not defined, and that leads to a null value
• once inside a set of double-curly brackets, do not add more

Please try this expression:

{{issue.summary.replace(fieldChange.fromString, fieldChange.toString)}}

Kind regards,
Bill

Thank you Bill!

Hello @Dan Spearing 

Welcome to Atlassian Community!

Could you please try to use this in the summary field?

{{issue.parent.Epic.name}}-{{issue.summary}}-Start

Let me know if this worked.

I can try, but I don't think that solves my problem because I don't know the child issue "suffix" strings at the time of the automation. Therefore. I can't use "Start", "Middle", and "End" when building the new child summary.
