I have created a custom Issue called INCIDENT. This has two custom fields- 'parent-Incident' and 'child-Incident'. The child incident has a field called - Parent-incident. The value for this field should be a drop down and coming from the in-progress parent-Incident ticket number.
I think the drop down value is always static. Is there any way I can get it done without any third party app?
or if there are any free app you suggest me to do it?
