When processing events from SAP, the connector uses the components illustrated in Figure 18 in the following ways:
An event is the execution of an ABAP function that transfers data to the listener. The event data sent by SAP may represent one or more such heterogeneous executions.
Each event from SAP is considered a transaction. The connector uses a two-step process with a Transaction ID (TID) to handle each event, guaranteeing once-only delivery of data from SAP to the connector.
