Grant Access to Records, Report and Dashboard Folders, and List Views by Territory
Where: This change applies to Lightning Experience and Salesforce Classic in Performance and Developer editions and in Enterprise and Unlimited editions with the Sales Cloud.
How: In Setup, select Territories or Territories and Subordinates when you create a sharing rule in Sharing Settings. Then specify territories. Only territories in your active territory model are available.
This sharing rule gives California reps (1) read/write access (2) to opportunities owned by Oregon reps (3).
Follow a similar process to share report folders (4), dashboard folders, and list views (5).
