New GL and Special GL- possible to repost to the correct profit center?

Question

Hi,
The scenario that I have is advance payment to vendor. The mandatory splitting characteristic is Profit Center (PC). The scenario is this:
(1) create down payment    :                
      Dr Advance Payment (special GL to vendor account): $12K,
        Cr Bank  $12K  (PC: 101)
In GL view, both lines will have PC: 101
(2) create vendor open line item :     
         Dr Domestic Travel expense (PC: 105): $7K
         Dr Insurance expense (PC: 104): $5K
             Cr Vendor: $12K
In GL view, Vendor line will be split with $7K under PC: 105 and $5K under PC: 104
(3) clear down payment     :                  
     Dr Vendor: $12K
        Cr Advance Payment (special GL to vendor account): $12K
In GL view, Vendor line will be split with $7K under PC: 105 and $5K under PC: 104.
Advance Payment line's PC remains as 101 as per step 1.
My question is at the 3rd step, is it possible to reverse the bank posting in step 1 and repost the bank line to split into PC: 104 and 105 since we now know the advance payment is for PC: 104 and 105? This is so that we can identify outgoing cashflow is for which PC.
Any help is much appreciated. I am open to all ideas, even coding for document splitting rule if it works.
Thank you.

Hi
It would not be possible in std. But you can look at writing your code through BADI AC_DOCUMENT
