Scheduling Alternate Resources application
You can define alternate availability for resources in your schedules.
You can override resource availability for the entire duration of the project, or for specific dates in the project.
For example, a project schedule is eight weeks long. During that period, 20 mechanics are available for the first four weeks. During the next two weeks, 15 mechanics are available. For the final two weeks, 18 mechanics are available. You can define the craft availability for each time period in the application. You can also define alternate availability for crew types and tools.
