Using the Query Resources feature, you can obtain a list of qualified resources based on a specific attribute set. However, you cannot use the list to assign work to resources, because Work Assignment does not consider the availability of resources while compiling the list. Also, Work Assignment does not reserve the resources that match the query.
The Query Resources feature returns a list of the first 50 resources that match the query. You can sort the list of resources based on Availability, Proficiency, or Least Occupancy. Work Assignment does not include the resources that are excluded from service.
