Yes, access to documents can be restricted to selected participants. Simply select the desired participants under “Access permission” when creating documents. TIP: The access permission can be changed directly in the list by right-clicking. In the project backup and for administrators, all documents are always available, even with access permission. Therefore we recommend to create a separate project for special sensitive documents like cost tracking, contracts, audits etc. and to invite only a small group of participants. This feature (document vault) is already available with the Midi package.
