1.4.2 Process chain control function

By using the process chain control function of JP1/AJS3 for EAP, you can run process chains defined on a SAP BW system from a non-SAP BW system. A process chain is a means of automatically running the jobs in a SAP BW system and consists of a series of processes (jobs) that are run in the background. By running a process chain, you can automatically run a series of processes based on the execution sequence.

JP1/AJS3 for EAP uses the BW - SCH interface, which is an external management interface for a SAP BW system, to control the process chains of the SAP BW system. The BW - SCH interface is an open interface provided by SAP for controlling the process chains of the SAP BW system from a non-SAP BW system.

To start a process chain, use the jbwipsta command. The jbwipsta command enables you to start a process chain already defined on a SAP BW system and monitor the process chain until the process chain ends. For details about the commands used with JP1/AJS3 for EAP, see 4. Commands.

Important
  • Any process chain started by this function is processed in the background. The process chain starts when the startup process job is executed. Before executing a process chain, make sure that there is an idle background work process.

    If you start a process chain when there is no idle background work process, the process chain waits for startup until a background work process becomes idle. If no background work process becomes idle within 10 minutes, the command terminates abnormally (and messages KAJM2803-E and KAJM2802-E is output).

  • While a process chain is being executed, do not start the same process chain. If you do, the process chain might not start or the currently running process chain might continue running because the response to the process chain start request has been lost (see SAP Note 833168).
