Share data extensions across an Enterprise 2.0 account in Email Studio.
Shared data extensions must exist in the main Shared Data Extensions folder or subfolder. From Shared Data Extensions, create and set permissions similar to other shared items. Move data extensions to the Shared Data Extensions folder to share the data extension with other accounts.
Note When you use AMPscript or queries, use the ENT prefix to reference a shared data
extension. This prefix indicates that the data extension exists at the parent level. The child
account’s permission restricts access to parent data extensions.
