What does the source Message Structure define regarding specific message types?

The source Message Structure is crucial in defining the layout and organization of specific message types within the Avaloq Message Interface. By identifying sequences and subsets of fields, it ensures that each message type adheres to a prescribed format that is clear and consistent. This structure delineates how different data elements are arranged and utilized within a message, helping both the sending and receiving systems understand how to process the information effectively.

This identification of sequences allows for the orderly processing of data, crucial in banking and financial applications where precision and reliability are key. It also aids in validation and parsing processes, allowing systems to recognize and extract specific fields based on their defined roles within a message.

While the other options present relevant aspects of messaging in general, such as length or potential communication channels, they do not encompass the primary function of defining how individual messages are structured in terms of their field arrangements. Thus, focusing on sequences and subsets of fields reflects the core purpose of the source Message Structure in the context of specific message types.
