Inbound processing is a runtime component that delivers messages to integration processes, or that starts new integration process instances.
You can configure inbound processing to improve performance and message throughput. The configuration that is most suitable in each case is determined by the semantics of the relevant integration process.
Inbound processing proceeds as follows.
Once the process type that the message is to be sent to has been determined, the message is placed in a process-type specific qRFC queue before being processed further in inbound processing.
You can influence this step by configuring how queues are assigned. Depending on the semantics of the process, you can either enable load balancing or execute the qRFC queue entries on a dedicated server.
For a message to be assigned to a process, the process must have at least one active correlation for the message concerned. If this is not the case but the process type contains one of the starting receive steps for this message, a new process instance is started and the message is sent to this process instance instead.
Once the message has been successfully delivered, the process is continued after the receive step.
You can influence this step by configuring the delivery mode.
SAP recommends that you select the setting without buffering where this is permitted by the semantics of the process. Selecting this setting can help with the analysis of specific problem situations. It will also improve system performance.
