Amount available
You can specify per resource type the number of resources that should be available per business event and per attendee. The required number of resources is derived from the information stored here when a business event is planned.
Alternative resource search
In the Alternative resource search, you specify the object type of a resource other than object type G, such as H for external person or M for material. (Only rooms and other resources have object type G.) You also specify the relationship between the business event type and the resource type Instructor or Material.

There is a direct relationship between object type R (resource type) and object type G (Room or Other resource) so that you do not need to make any further entries for resources that have object type G. They are offered automatically for selection during resource reservation. The reason you must make additional specifications in the Alternative resource search is to ensure that the system offers and finds resources that do not have object type G.
If you select resources that belong to the category instructor or material here, the system automatically defaults the pertinent object types and relationships in the alternative resource search. For instructors, the entry * (asterisk) is the default object type. This stands for all object types. If you do not want to restrict the search to a specific object type, you can reserve instructors with different object types for your business events.
In addition, you must also specify the relationships between the business event type and the material ID or the instructor ID.
