11.2.2 Data Monitor
The Data Monitor tool is used to monitor data transactions for specified parts. The transaction
list is updated whenever data changes are triggered. Several data Monitors can open to
monitor specific part types.
The
Title bar
of the Data Monitor dialog displays the monitor number. This is useful when
more than one Data Monitor is open.

for a snapshot of transaction history.
All Object

Monitor Object:
Select the parts to monitor. If there are no parts of the type selected, the transaction list does not update
that part type; other types on active windows are updated.
