The types of operations performed might enable you to determine the activity report that was generated directly before, or after, the current activity report.
For example, an activity report details that an MCA sent a message from a transmission queue down a channel. The last operation detailed in the activity report has an OperationType of send and details that the message was sent using the channel, CH1, to the destination queue manager, QM1. This means that the next activity performed on the message will have occurred on queue manager, QM1, and that it will have begun with a receive operation from channel, CH1. By using this information you can identify the next activity report, providing it exists and has been acquired.
You can determine the general order of the activities from the dates and times of the operations in each activity report.
Warning: Unless every queue manager in the queue manager network has their system clocks synchronized, ordering by date and time does not guarantee that the activity reports are in the correct sequence. You must establish the order manually.
