The DeletedItems property returns a table containing a list of all deleted items in the schedule file.
Schedule object
Object (Table)
Read/write
Only the owner of the schedule file can read the DeletedItems table. The DeletedItems property can be used with the ChangeNumber property to synchronize different copies of a schedule file. For example, an application can determine which items in one copy of a schedule have been deleted, and then determine whether these items have also been deleted from another copy of the schedule.
Items in the DeletedItems table are permanently removed from the schedule and cannot be recovered.
