In Enterprise Studio you can share a model package with other people and control their access to it by inviting them. You can share model packages you are contributing to yourself, and give edit permissions for models and folders in this model package that you can edit yourself. You can invite any person you like, but you may be limited to only invite existing users and user groups with the (Lead) Designer role.

Required roles

  2. On the File tab, click Manage Package, and then click Share.

Invitation notification

Invited people that are not yet registered in Horizzon will receive an e-mail message with an invitation to register. After registration, they can start contributing to the model package.

Invited people that are already registered in Horizzon do not receive an e-mail message. Instead, they are informed about the invitation via their Activity Console. They can directly start contributing to the model package after opening it.

Use the link below the Invite button to see which people have already been invited. When clicking the link, Horizzon is opened in your web browser showing the model package with its projects and participants.
