1. Workday Tenants
Production tenant is the one that is used by the organizations to manage their data. This tenant contains all the live data of an organization and hence it needs to be maintained very carefully. We do not recommend changing production data directly in this tenant. This can lead to inconsistency in live system and business may suffer because of it.
Sandbox or test environment is a copy of production environment where all the data from production environment can be copied into it without affecting any business process or operations. It allows changes to be tested without impacting any real processes or workflows in your organization using live data that has been imported into your Sandbox tenant. A sandbox environment lets you see how different changes, such as new features, customizations, and integrations will affect your current system before you implement them for everyone in your organization.
