In RIVO, the Organization Structure represents any kind of Organization/Company(Corporates/Banks) that is used in the System.
This Structure contains the details of the Organization and all the Organization sub-units involved.

The Organization structure and units, with their users is maintained by the Admin user of the Specific Organization(Corporates/Banks).

There can be a multiple levels of Organization for a specific parent unit.

You can model your organization in several ways; 

• Simple, flat structure. Everyone in the same structure. Everyone can see everything
• By Line of Business.  Split the organization into units with the same Product , e.g.  LCs in one unit and Guarantees in another.   You can set the permissions of the users in the unit so that they are restricted to Deals from that unit , or have global permission.  
• By Geography. If your Organization is split by Geography, you can replicate that in RIVO too.
  Again, the permissions of the users can be restricted to Deals from that unit , or have global permission. 

Within each Unit , you can then add in the Users , and set their Permissions 

To access the Organization Structure in RIVO, Go to the Administrator menu and then select the option Organization Structure.
