Functionality
With this method you can determine the resources that are currentlyavailable to the background processing system in an R/3 System. Theresources are determined across the system taking into considering theactive operation mode. For each instance, the system returns the numberof 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 may be useful, for example, if a job should be startedimmediately. With this method you can then determine whether backgroundwork processes can now be made available.
