With the release of Dynamics GP2010 Microsoft released a new Dynamics Client for Office (DCO) license that have now been renamed as Light Users. A number of ISV modules now require end users to purchase Light User GP licenses.
Per the new licensing, a Light User license is required for any user who does not have a full Microsoft Dynamics GP user license but who accesses Dynamics GP data from any other software program outside of GP.
An ESS (Employee Self Service) license is required for any user who through means other than the rich client UI for only the following use cases:
Employee Administration
Employee Time and Attendance
Employee Travel and Expenses
Employee Requisitions
Limited Use licenses are only available to clients on Business Ready Licensing.
