We have our change management tickets setup in Jira. I have a custom date filled called "Change Date & Time" and also another Custom field called "Change type" with 3 options, Emergency, Standard, and Change Model. Is there any way that I can have a validation of some sort so that if a user creates a change ticket, and the date of their change is not at least 7 days out from that moment, that it throws an error saying they must set their change as an Emergency change?
