Backup Exec licenses

Hi,

I have some question in regard of the Backup Exec Licenses.

In my environment, there are mixture of BE ala carte license  includes BE MEdia Server and VRay edition license. 

After key in all serial number ( all a la carte + Vray ) , Vray edition licenses is showed

My questions are:

1. Since the environment consists of BE MEdia Server license and Vray edition license. How the sequence of the licenses been read by BE. Is there any specific sequence if I would like to use the license of the  BE Media Server a la carte licenses?

2.  There are 2 x BE hyper-V agent licenses and 2 x Vray-edition licenses. What is the column "Licenses Used" means from the report as showed below

Thank you

Charmaine
