ERP Regions 
Note
The following information is relevant only if you integrate SAP Sourcing with SAP ERP. For more information, see Integration of SAP Sourcing and SAP ERP.
In some countries, the region forms part of the address. The meaning depends on the country. For example, in the United States, the region is the state (such as California or Oregon); in Canada, the region is the province (such as British Columbia or Quebec).
The regions in SAP ERP are required in SAP Sourcing to publish vendors from SAP ERP to SAP Sourcing successfully, and vice versa.
Typically, ERP regions are made available in SAP Sourcing through workbooks. However, you can also define ERP regions in SAP Sourcing manually, as described below.
The region must exist in SAP ERP before you create it in SAP Sourcing.
