What must be done for RefArch to use the same customer list as RefArchGlobal?

To enable RefArch to utilize the same customer list as RefArchGlobal, selecting RefArchGlobal in the dropdown for Customer List is the correct approach. This option allows you to define the specific customer list that the RefArch site should reference, effectively establishing a direct link to the existing customer list within RefArchGlobal.

This method ensures that the RefArch site can seamlessly access the customer data stored under RefArchGlobal without the need for additional imports or configurations specific to data sharing settings. By making this selection, RefArch becomes capable of synchronizing customer information directly, which can enhance user experience and maintain consistency across different site environments.

This option stands out as the most straightforward and direct method for achieving the desired functionality, simplifying the management of customer data across related sites. In contrast, importing customer lists or enabling sharing options at a global or site level may introduce unnecessary complexities or data redundancy that do not directly address the objective of using a common customer list.
