How can I manually add territories to an opportunity?

You can manually assign territories to one or more additional salespeople on a product line in order to allow another salesperson working the deal to forecast it in his territory.

Manual assignment may be required, for example, to even out a temporary unbalanced load between salespeople reporting to a manager, or to accommodate a salesperson on extended vacation. You manually assign territories in the assign sales credit screens or in the details of the revenue line by using the territory list of values.

You must have the Sales Administrator job role to perform manual territory assignment on opportunities.
