can we configure a dynamic key string like XXX-<today date> while creating a project

[Pooja Maurya]

The key to create new issues in a project are understood to be static - like xxx, or yyyy, etc. 

Can we configure dynamic keys e.g., some part static and another part based on current date, etc ??

Hi @Pooja Maurya 
Welcome to the Community !
That's not possible as the whole JIRA system is based on this architecture only. i.e. KEY-<Number>

You can have an additional field created that would be read only and it will have value based as KEY-<Date>-Number via the automation

Trigger: Issue Create
Action: Edit field -> {{project.key}}-{{now.format("dd/mm/yy")}}-{{issue.key.split("-").get(1)}}
