This is for electronic schedules which come into the laboratory and the scheduler has added the extra tests to the same schedule and just updated the schedule name.
The first schedule would go into KeyLAB correctly. In this example the schedule has classification tests and the client is going to add advanced test at a later date.
When the second schedule comes in it still has the classification tests for the samples on along with the extra advanced tests.
If we added this schedule we would duplicate the classification tests. If you use the remove duplicate tests button it will look for the those samples with that test name. if it finds any on other schedules for that projects it will remove them.
