Which of the following is a characteristic of the outgoing message definition?

The characteristic that the outgoing message definition generates the Message Builder is fundamentally linked to its purpose within the Avaloq Message Interface framework. The outgoing message definition is a crucial component that facilitates the preparation and structuring of messages that are sent out from the system. The Message Builder acts as a tool that takes the specifications defined in the outgoing message definition and creates a structured message according to the defined parameters.

When an outgoing message definition is established, it outlines how messages should be formatted, what data fields are included, and how these fields are to be populated. This process is essential for ensuring that outgoing messages are constructed correctly and conform to the necessary standards for the receiving systems or parties.

In contrast to this correct understanding, the other options do not align with the functions and capabilities of the outgoing message definition. For instance, the notion of it being used solely for incoming messages contradicts the definition's intended purpose, which is clearly for outgoing communications. Additionally, the inability to modify an outgoing message definition does not hold true, as these definitions are typically adjustable to meet evolving communication requirements. Lastly, an outgoing message definition must indeed be based on fields because it defines what data is included in the message; it cannot operate without referencing fields for the data being transmitted. Therefore,
