Role level security

Role level security for multiple organization levels Hello, Can anyone share an example of how to set role level security for the same user so they have access to the whole company but can drill down to only the level they manage? For example, "Company A" has 5 territories. Everyone in the company should be able to see company level sales results but if Territory Manager 1 drills down into customer level detail, the details would only contain customers with sales in Territory 1.
