The Rep_Roster_vod object stores information related to Territory Management processing, the relationship between users and territories, as well as user-related HR information, for example, address and asset tag.
The Username_External_Id_vod field on the Rep_Roster_vod object must match the User Name field for the corresponding record for the user in the User object. This value is the user's login id. The Username_External_Id_vod field utilizes the Transfer Sample Transaction to identify the Address for a Transfer Sample Transaction based on the Address fields in the Rep_Roster_vod object.
To meet compliance regulations, the Address fields in the Rep_Roster_vod object maintain Sample Storage information for all Sampling users.
Admins can add custom fields to this object.
