To maximize the chances of finding a resource, you can use the Queue to Multiple feature. This feature is applicable only when you are requesting a single resource. This feature serves as a single-step execution of multiple Request Resource operations. When there is a single resource, Work Assignment attempts to find the best available resource in multiple services. If Work Assignment does not find any resource, the system queues the work against multiple services. If Work Assignment finds multiple resources, the system selects the best resource based on rank or Resource Selection Strategy steps, such as proficiency or occupancy. The system reserves the resource after the resource is finalized.
