The Entities panel of the Administration tab has one button, Entity administration, which opens the list of entities of the installation: identifier, name and description, with New, Edit and Delete.
An entity is a company, site or department the batches belong to. Every batch carries an entity (chosen in the Create Batch window) and, in ChronoScan Enterprise, the users are assigned to entities and can be limited to see only the batches of their own. See Entities.
