Which of the following statement regarding the SAPInput Node is true?
A. DFDL domain can be used to model ALE configuration and IDocs.
B. The SAPInput Node must always be paired with the SAPReply Node in the same message flow.
C. When the processing in the message flow is done, the SAPReply Node opens a new connection to the SAP program and send the response back to SAP.
D. When a listener receives a call from SAP in synchronous mode, it blocks processing until the message can be picked up by an available message flow instance that contains the SAPInput Node.
Correct Answer: D
Explanation/Reference:
Explanation:
You can improve performance by configuring the number of listeners on the adapter and the number of additional instances on the message flow to prevent delays when processing synchronous calls from SAP.
When the listener receives a call from SAP, it blocks processing until a message flow instance that contains the SAPInput node is available. When a message flow instance has become available, and has started to process the import parameters, the listener again blocks processing until a message that contains the export parameters is propagated to an SAPReply node.
Incorrect Answers:
B: You can use a SAPReply node in the same message flow as an SAPInput node, or in a different flow from an SAPInput node. The SAPReply node must be deployed in the same integration server as the SAPInput node.
