What is the source type used in outgoing message definitions?

In the context of outgoing message definitions within the Avaloq Message Interface (AMI), the source type specifically identifies the type of message being sent from the system. The designation 'MSG OUT' refers directly to outgoing messages, which are those messages that are generated and transmitted from the system to external parties or systems.

This term reflects the nature of the message in terms of its operation, highlighting that it is intended to leave the system rather than being received or processed internally. Thus, when defining outgoing messages, 'MSG OUT' is the appropriate classification to use, adequately signaling that these messages are part of the outbound communication flow.

The other options represent different facets of message handling or communication types but do not specifically denote outgoing messages. For instance, 'MSG IN' denotes incoming messages, 'MSG TRANSFER' may refer to the movement or transport of messages (not exclusively outgoing), and 'MSG PROCESS' could relate to the processing of messages but not their directionality. Therefore, the correct designation for outgoing message definitions is indeed 'MSG OUT.'
