Job Name can be edited for a Batch Request in Hold or Wait status.
When a Batch Request is submitted with a Job Name, if the user does not belong to the SECURITY user group, the Job Name cannot be assigned if it has already been assigned to another job created by a different user.
In the case where a job with a Job Name is on hold and another job with the same Job Name that has a lower priority is not on hold, the job with lower priority will be executed ahead of the one with higher priority that is on hold.
