permissionVersion

Specifies the version number to delete.

You can't delete the default version for a customer managed permission.

You can't delete a version if it's the only version of the permission. You must either first create another version, or delete the permission completely.

You can't delete a version if it is attached to any resource shares. If the version is the default, you must first use SetDefaultPermissionVersion to set a different version as the default for the customer managed permission, and then use AssociateResourceSharePermission to update your resource shares to use the new default version.
