How to restrict status change of jira ticket in specific conditions?

[Vasundhara Verma]

Hi , I have a scenario where I have to restrict the state change of jira ticket when the field values of 'Reporter' and 'Approver' is same. 

For example, I have a workflow, where when a ticket is raised is in 'Pending Approval' state and limited members can change their state to 'Approved' or 'Rejected'. So the Reporter has to mention the person's name in custom field 'Approver'.

So I need to put the restriction that if the reporter and Approver is the same person, he/she should not be able to change the state of the ticket.

Thanks

Ah, yes, the problem is "a few years old".  JIRA 7.something has more functions.

Try

fixversion in versionMatch("regex")
