What defines the sequence of fields in the outgoing message?

The sequence of fields in the outgoing message is defined by the structure of the message itself, which is encapsulated in what is referred to as the Message Struct Source. This concept outlines how data elements are organized and formatted within a message before it is transmitted. The Message Struct Source ensures that all required fields are included in the correct order, allowing for proper interpretation and processing by the recipient system.

Understanding the structure of a message is critical, especially in the context of financial applications where precise data handling is essential. The layout dictated by the Message Struct Source provides a clear blueprint that guides how information is serialized into a message format suitable for transmission over the network. This structured approach enhances data integrity and communication efficiency, particularly important in complex systems like Avaloq's.

The other concepts, such as Network Source, Outgoing Message Source, and Message Engine, play supporting roles in the message transmission process but do not directly determine the order of fields within the outgoing message. They facilitate the transmission and management of messages but do not define the specific structural aspects that the Message Struct Source does.
