How to handle partial payment in A/R Aging report buckets

Question

Hello ALL,
         In FIAR_C03 cube we have Item status field and only two values are comming there
         O or C.
          But in R/3 there are some partial payment concept. BI considering partial payment as a open item.
           Example
       We have a invoice of 10,000 USD
       now one payment of 5,000 came from customer side and we settled 5,000 against above invoice
      now remaining is 5,000.
      means 5,000 of payment and 5,000 of invioce should be closed or cleared . But this is not the case becuase of invoice
      is not fully settled. When invoice will settled fully then it will become cleared.
   using open item we are making our AR aging buckets but now 5,000 payment is still open actually its
  cleared and net due date of this payment is different then net due date of invoice thats why
  these two entries are coming in two different aging buckets so the balances are coming different.
How can we handle this scenario in SAP BI during making of AR aging.
Any help highly appreciated.
Thanks,
Sneha

There is an OSS note dealing with this 522235 - its shows how to use a virtual char to do this (ie change the due date at runtime)
This tends to be viewed more as a business process problem - the users woul dlike the part payment to be aged the same as the invoice it's against (like the std R3 aging reports) - I actually like the BW way as it highlights the fact the cach collectors are not doing their jobs of clearing down the debt - problem is now they will all go and create resicual items
