To respond to all AQ's (Additional Information Request Inquiry), which message key should be used?

The message key used to respond to all Additional Information Request Inquiries is AR, which stands for Additional Reply. This key indicates that the response is specifically addressing a prior inquiry for additional information. When handling queries or requests for further details in the context of the Indiana Data and Communications System (IDACS), it is crucial to denote that a reply is being provided, thereby facilitating clear communication and tracking of information exchanges.

Using the AR key ensures that the communication is correctly categorized, allowing all involved parties to understand that the message is a direct response to an inquiry, rather than a new request or process initiation. Properly utilizing message keys enhances the efficiency and clarity of information sharing within the system.
