Universal Containers has a requirement to share Accounts automatically to the users at a field office. They currently have the following setup in their environment:
Accounts are set to Private in the Org-Wide Default.
The field office is specified by a lookup in the account object.
There are 400 field offices.
The users in each field office are managed using public groups.
Based upon a lookup relationship field on the Account, how should the Architect meet their requirement?
