One of the major drawbacks of the base Microsoft Dynamics NAV product is the ability to schedule reports, or the lack thereof. With the release of Microsoft Dynamics NAV 2018, you can now schedule any reports to be run on a certain date and at a certain time using Job Queue.
Job Queue is a feature in Microsoft Dynamics NAV that was introduced in version 4.0. It basically allows you to schedule processes to run at a certain time on a specific day. Reports are scheduled using Job Queue. Job Queue should run in the background while using NAS (short for Navision Application Server) for a report to be scheduled properly.
