Considerations While Working With Master Reference Geographies

Master reference geographies are the definitive, single-source-of-truth geographical data used as the foundation for defining and maintaining geographical boundaries and types. These predefined geographies, like countries, states, and cities, are essential for storing address information and creating geographical hierarchies that drive various business processes across enterprise applications suites.

Considerations for working with master geographies:

• You can update master geographies using the Manage Geographies page, but you can't update master geographies using Import Management.
• Countries are predefined so you can’t delete them. You can delete the geography levels of a country in the geography hierarchy, such as state, city, and so on using the Manage Geographies page.
• If you delete the geography levels of a country in the geography hierarchy, such as state, city, and so on, you must manage the impact of these changes in the downstream applications, such as SCM, ERP, HCM, and so on.
• If you delete a geography level, all the children in that geography hierarchy are also deleted. For example, if you define city and postal codes under a state, and you later delete the state, all the cities and postal codes under this state are also deleted.
