Maintain Service Providers 
A service provider can be a person, group, contractor, or organization that provides services for a company. You maintain service providers within the system, to make them available for scheduling.
When you display the details for a service provider, the account details and service arrangements are most relevant for service resource planning. For more information about service arrangements, see Service Arrangements and Service Arrangements for Service Providers.
You maintain the information about the service provider's basic availability, using the Availability assignment block in the service arrangement.
For more information, see Time Allocation: Basic Availability.
You enter extraordinary time allocations by selecting Time Allocations in the result list of the resource search.
For more information, see Time Allocation: Extraordinary Availability.
