View History shows a history "log" of a scheme in the Notification Manager. The information displayed includes:
An activity (such as "Created", "Completed")
The time when the activity took place
The user that performed the activity
The source of the activity - either Completed or Configuration (this distinction is necessary because a scheme that has been completed can be copied back to construction, carrying the same name in both places)
Details: for some activities, especially when an error occurs, there will be some information in this field
The list can be sorted on a column by clicking on the column label.
