Creating Chain Definitions for Multiple SAP Systems

The SAP jobs of a chain definition require parameters, there are two parameter classes, scheduling parameters and chain process parameters.

Scheduling parameters define the status of the chain at submit time, the queue and the priority of the process.

For SAP jobs, the queue defines the SAP System where the job runs, when the SAP System parameter is not set.
