Reversing interim cost account posting

Question

Situation is like this:
1)-we recieve payments (BP unknown)
2)-payment to a ''parking'' account is carried out.
3)-afterwards we come to know of the actual BP and we clear the open items for that BP.
I need to know Point 3. because the Payment lot is closed( as in Point 2)
I have rec'd some tips in form of:-
-respective FI lines need to be searched. (how)
-reverse those financial lines   (how)
-create new payment lot (how)
-and then finally assigning it to the u2018knownu2019 BPu2019s open item
I need some help on the 'hows'
Thanks in advance

-respective FI lines need to be searched. (how)
Use T-Code FP30 to search a payment.
-reverse those financial lines (how)
Use FP08 for Ind reversal and FP08M for mass reversal
-create new payment lot (how)
Use FP05 to create a new payment lot. Ideally this is not required as in the first instance itself the items goest to clarification /suspense account. either using FPCPL or FP05, you can clarify the item
-and then finally assigning it to the u2018knownu2019 BPu2019s open item
Use either  FPCPL or FP05, to clarify the item
hope this helps
