Prioritizing messages in the queue - DADM CS

The DADM CS call is advisable if, at a given point in time, several messages are in the processing queue for the same recipient. Using DADM CS, the specified message, identified by its job ID and the time it was created, is moved to first position in the message queue. You can determine the job ID and the time of the message’s creation using
DADM RQ.

Please note that you can only prioritize time-driven messages if the “earliest execution time” specified by DPUT at the time of the message’s creation has already elapsed. Otherwise, UTM rejects the DADM-CS call (return code 40Z).

See section "KDCDADM NEXT" in chapter "NEXT - Prioritize messages in the message queue".
