Permission Set Extension Object

APPLIES TO: Business Central 2021 release wave 1 (v18.0) and later

The permission set extension object in Business Central adds permissions to an existing permission set defined in AL. A permission set extension object cannot remove permissions from an existing permission set, it can only add permissions. If you, for example, add an extension to Business Central, you can use permission set extension objects to grant permissions to the objects in your extension. This means that the admin of Business Central does not have to assign additional permission sets to the users, because that automatically happens when the extension is installed, and the permissions go away if the extension is uninstalled.

For information about which permissions can be assigned to objects, see Permissions on Database Objects.

Designing with cautiousness

If a permission set is extended through AL, that extension will make additive changes to the permission set. This means that an extension can provide elevated privileges to an otherwise limited set of permissions. Building permission sets that can be extended must be done carefully with this in mind.

Snippet support

Typing the shortcut tpermissionsetextension will create the basic layout for a permission set extension object when using the AL Language extension in Visual Studio Code.
