Note: In Coeus, department are referred to as Units (i.e. "business units").  PEER inherits this terminology, so Department and Unit mean the same thing.

You cannot directly add a new Unit to PEER. New entries must be validated before they are created to ensure information is correct and any additions are not duplicates of existing records.

To request a new Unit be added to PEER, you'll want to submit an Action Request in PEER.  Please see the article Submitting an Action Request, and select the Action Request called "Add a Unit to PEER".
