Which of the following statements regarding AMI message types is true?

The statement regarding internal messages influencing order handling is accurate. Internal messages within the Avaloq Message Interface (AMI) are crucial as they can carry information that directly impacts various operational processes, including order handling. These messages can communicate event notifications, status updates, or modifications that are essential for decision-making within the system.

In the context of AMI, internal messages facilitate smooth operations by enabling components within the financial system to react to changes or maintain synchronization with external processes or events. Their ability to influence order handling means they play a pivotal role in ensuring that transactions are processed correctly and efficiently, reflecting the dynamic nature of financial operations.

On the other hand, the other statements provided do not align with the functionalities of the AMI messaging types. For instance, MSG_EXTL_OUT is designated for outbound messages, while MSG_EXTL_IN is specifically meant for inbound messages. These designations make it clear that these external messages do not influence processes in the same manner as internal messages do. Additionally, stating that neither message type impacts transactions overlooks the vital role of internal messages in operational workflows.
