Change territory geography
It is highly recommended that you choose the correct country/region and the applicable geographic unit that compose your territories at the time you are creating them. If you change the geography of the current territory set, all the territories that have been created are deleted from the map. In addition, changing the geography of the territory set will remove any data mapped to the territories in that set.
In the Territory Manager, click the Change geographies.
In the Country/Region box, click the country or region that applies to your territory data.
Note If the territory set consists of multiple countries, choose <Multi/Other>.
In the Geographic unit box, click the geographic unit that comprises your territories.
Note You must select the smallest common geographical unit that applies to your territories.
