Hello. Is it possible to make a behaviour, where based on the Jql filter, it will be determined whether there is an entity that occurs once in a custom field of the “issuepicker” type in existing tasks, and then change another field?
I mean logic: there is a situation when you want to creat issue with special custom field issuepicker “A” that has issue “B” inside (you chose it)
than behaviour works like:
“Jql filter” - “finding previous tasks in project with a custom field issuepicker “A” with one issue “B” inside (every time it can be different issue “B”, but this is can only be chosen once in all tasks)” - “blocking possibility to choose “1” in custom field “C” in the same issue (list type field)”
I know it was difficult to explain, sorry for that
