Why can't user re-assigning issue to someone else in Jira Server

[Sharon Curtis]

I have a user that is not able to re-assign the ticket back to the Reporter.   Why can't the user assign ticket back to reporter?

Can the user assign the issue to a different person, other than the Reporter?

Two things to check:

1. If the user is able to assign the issue to another person other than the Reporter, then check if the Reporter a member of a group or role that has the Assignable User permission in the Permission Scheme associated with the project.

2. If the user is not able to assign the issue any other person, then check if the user is a member of a group or role that has the Assign Issue permission in the Permission Scheme associated with the project.

The fix was I updated the permission  for Assignable User  and added value of Anylogged in user.
