This table provides a persistent store for dispatch messages generated as result of changes to jobs and standard activities, so that they can be recovered in the event of system failure. It is not a complete copy of all messages that are waiting to dispatch. Once a message from this table has delivered successfully it is deleted from the table.

HouseKeeping

This table is tidied by sp_dbtidy’s Global group (messages that have lost their ‘posting’ as the engineer has move to another FRU), and by the Job group (specific jobs)
