Clearing Reset not done in /dbm/cashdesk

HI Expert,

I am trying to cancel a downpayment request been clearing in /dbm/cashdesk with cash document no. 001

Now i would like to reset and reverse cash document no.001 and i will put cash document no.001 in "Cancel" tab and press "cancel cash document", but system only perform reverse cash document no.001 and not reset it.

Therefore, my downpayment request reseting is pending half way and i cannot process with clearing downpayment again in /dbm/cashdesk.

Please advice any configure or snote i need to apply it?

Thanks.
