Functionality
With this method you can determine the resources that are available inan R/3 System at a specific time. The resources are determined accrossthe system, taking into account the operative mode active at thespecified time. For each R/3 instance, the system returns the number ofof work processes for the background processing system, as well as thenumber of work processes that are reserved for jobs in priority classA.
This type of check of the available resources is not absolutelynecessary. A background job is always executed unless the backgroundprocessing system is completely out of operation.
the check can be useful if, for example, a job is executed at theexecution time without any hesitation. With this function module youcan then specify whether any background work processes may beavailable.
