Hi Muhammad,
We request you to kindly click on the "Start new Discussion" link to raise your queries in future instead of the "create new document" link

Regarding this issue, could you please update the thread with the complete error message you are seeing when you try cancellation?

Regards
Krishna

Thanks,

Muhammad Daniyal
