Districts are user-definable groupings of geographical areas within a country. Districts can provide flexibility in reporting, data collection, and marketing campaigns.
If states are configured for the country, you can set up districts consisting of the following combinations:
Country/state/city
Country/state/postal code
Country/state/city/postal code.
For example, one district in the United States might include the cities of Chicago IL, North Chicago IL, and Racine WI. Another district might include the entire state of Delaware, the city of Philadelphia PA, and postal codes 08101 through 08104 in Camden NJ.
If the country has not been configured using states, you can set up districts that consist of any cities within a country. For example, you could set up a district such as the Netherlands consisting of the cities of Rotterdam and Delft.
