Southwest Airlines is seeking advice from other users on Cancel Task functionality on Blocks and Requirements with scheduling rules.  

Current functionality when a task is cancelled tracking reverts to initial schedule.  This drives the task 90% of the time overdue and locks the aircraft until manually updated.  

In the case of Block Chain tasks it reverts back to 1st occurrence of the chain.  The response from IFS has been this is how Maintenix was designed.  

We do our best to communicate to frontline users to not cancel any tasks other then Job Cards, but occurrences of cancelling Requirements and Blocks still occur.

Any insight on this would be appreciated.
