An address type indicates the role an address plays in the business processes of your organization. For example, an address of the Supplier type refers to a company that provides your organization with office supplies.

You can use the Address type selection step to add or retrieve addresses of a particular address type. By selecting an address type in this selection step, you can retrieve all addresses of this particular type at the Addresses selection level.

If you select an address type at the Components selection level and add a new address at the next level, the Address type field will automatically inherit the name of the selected address type. If you want to work with prefiltered pick lists in other TSIs which must contain only the addresses of a particular address type, you can define this in the FieldDefiner TSI.
