You use the Gantt view to assign upcoming work to labor and crews based on their availability.
Assignments typically originate from a job plan, but can be added to work records at any time. Job plans specify the crafts and crew types that are required to do the work. When applied to a work record, the work plan contains these work requirements, which you can then assign out to labor or crews.
The resource chart in the Gantt view displays labor and crew availability as it is defined in the Calendars application, where you can define calendar, shift, and break information. Non-work time appears in the Gantt view as a shaded area on the resource table. The Gantt view also shows the modified availability of the resources, including overtime, sick, and vacation time.
