Defining RFC Groups for Parallel-Processed Jobs
Asynchronous remote function calls (RFCs) prevent parallel-processed jobs from overusing SAP System resources. For more information, seeParallel Processing of Jobs with Asynchronous RFC.
By default, a parallel-processed job uses all qualified servers in an SAP System according to automatic resource-allocation rules. However, by defining RFC groups, you can control which servers can be used for parallel-processed jobs. An RFC group specifies the set of allowed servers for a particular parallel-processed job. The group used for a particular job step must be specified in the job-step program in the keyword CALL FUNCTION STARTING NEW TASK DESTINATION IN GROUP.
For information on how to configure customization for setting up RFC groups for parallel-processed background reports, see application documentation.
RFC groups can allow different parallel-processed jobs to run at the same time without competing for the same servers. In this case, the different groups used by the jobs would specify different sets of servers.
RFC groups can also separate parallel-processed jobs from servers being used by dialog users. In this case, the group used by a job would name servers other than those in the logon groups for users.
