The Confirm activity confirms any confirmable messages received by the process instance. For example, if a process is started because of the receipt of an RVCM message, the Confirm activity can send a confirmation message to the publisher of the RVCM message.
See Checkpoints and the Confirm Activity for more information about using the Checkpoint and Confirm activities in a process definition.
In case of the Service Resource operation process, perform Auto-confirm in case of clientAck after the end Activity which would still work even if you are not using Confirm Activity in the Operation Process.
