Can i Link an issue when two fields match

[daniel_hedberg]

Im trying to figure out if Automation for Jira can Link an Issue when i create an issue. 

What i would like to happen is that we have a Custom customer field in two different projects  CON and Customer.

When i create a issue in the project CON and fill in the Customer field id like for Automation to check if its the correct project and that the field is not empty that is easy to do with a JQL.

But what i would then want to check is that if their is a corresponding issue in the project Customer and if there is Link these issues together.

Hey there Erik,

Sounds like you might want something like below:

1. Add a trigger on Field value changed for your "CON" project and the "Customer field" value changes
2. Add a "Related issues/branch"
   1. Pick JQL from the list
   2. Add a JQL to look for matching issues in "Customer" project. Something like: 
      1. project = Customer AND "Customer field" = "{{issue.Customer field}}"
3. Add an action to link back to the "Trigger issue"

Let me know how that goes!

Cheers,
