Actually I just saw that you were the originator of that post as well - I take it you are doing a lot of SDSF automation but not a lot of thinking? Try to think - if you can release a job from an input queue, can you cancel a job from an active or output queue?
Try to put a little thought into your questions in future. I don't mind taking 10 minutes from my working day to check out any quick answers I can provide, but if you waste my and other people's time with repeated questions slightly altered you will be ignored.
