payment request in cash concentration mass run F9H6

Hi,

I  ran  cash concentration run -F9H6  (  periodic processing in IHC)  and  there are payment requests  generated.  These are   then paid in F111.

There are  payments requests which are not  required to be paid  and   the use  want it to be deleted. 

I  tried  using F8REV   and it  says that  it is only for online payments ( free form payments).  I  tried  archiving,  but the archiving object for payment request is not seen  in     Inhouse cash -Environment -Archiving. .

Below  is  the  report  in F8BT  for  the  open payment  request ( called  key number  -1st column )

Key number CoCd DocumentNo Year Currency   Pymt curr.amnt AccTy Partner    Alt. payee

6616                      GB99                 EUR                 0,03- S     1553214xxx

Please  provide your  suggestion on  how to delete the  payment request  generated in  F9H6.

Thanks
