When you have a new Tenancy Manager you would like to add to Chintaro, from the Home Screen, click Tenancies then Tenancy Managers. 

Click the Add Manager button at the top of the screen:

Enter the relevant information about the Tenancy Manager (if they are internal to your Organisation, you may only need to enter the Manager Name and Chintaro Username):

Exit the screen to save the record. You can now assign Tenancies to the new Tenancy Manager. 

If the Tenancy Manager you just added is taking over someone else's Tenancies, you can reassign Tenancies in Bulk: How to reassign a Tenants to another Tenancy Manager
