Remarks

In multi-tenant applications, the host database can maintain shared business objects. Tenants can read this data, but cannot modify it. Host UI administrators have complete CRUD control over host and tenant data.

Call the CreateObjectSpace method to create an object space to access the following data:

• Tenant business objects from the host account
• Host-shared business objects from a tenant account

Refer to the following help topic for more information: Shared Data Support in a Multi-Tenant Application.

Tip

In a tenant account, you can use CreateObjectSpace methods without the tenantName parameter to get the same result.
