If you run Auto Schedule more than once it keeps changing the result in OWB. If the data is the same then ideally once Auto-schedule has been executed it should not be changing the data no matter how many times the Button is clicked.
Steps to Reproduce:
Expected result: After running Auto Schedule the second time nothing should change in the Gantt
Actual result: After running Auto schedule the second time the Gantt changes again
