Hi Mar Angelo - Welcome to the Atlassian Community!

I would suggest that you have a multi-step approval process and when the issue moves into the status prior to the last approval status, then populate the Approvers field with the value of the Reporter using an automation rule.

Can you give me a fully detailed?

I already try it, but I can find the reporter field to assign on last approver

Can you share what you have so far? Are you using an automation rule to populate the Approvers field with the Reporter?
