Map custom Progress Status based on status of Parent and Child Issue

[Sam P]

Hi,

I have a structure that looks like following. 

Parent Issue Type "Feature" with Component "LEVEL1"

       Child Issue Type "Story"

The status of Parent Issue Type and status of Child Issue Type needs to be mapped to a custom status and displayed in the formula column at Parent Issue Type row.

READY -> OPEN -> Backlog1

READY -> READY -> Backlog2

IN PROGRSS -> IN PROGRSS -> Build In Progress

IN PROGRSS -> IN QA PROGRSS -> Build Completed

Also, things to consider:

1. There may not be any Child Issue Type created or linked to Parent Issue so mapped custom status needs to be "Product Backlog"

2. If there are multiple Child Issue Types, how do I handle it?

Any help would be appreciated!

Thank you very much!
