Base and Attach licenses

With the CRM and ERP apps, if there are users within an organization who need to be licensed for more than one app then Base and Attach licenses are a cost-effective way of doing this. The Dynamics 365 Remote Assist product can be acquired as an Attach license for a Field Service Base license but can’t itself be used as a Base license for any other products. Thus if, for example, a user needs to be licensed for Customer Service Enterprise and Dynamics 365 Remote Assist, then a Base license for each product would be required.
