AR Details update

We had an unapplied receipt of $10000 and we applied some invoices against that.  But after applying the invoices we found that the Payment amount (RAAP) has been updated short of the actual gross amount.  For ex. Invoice gross amount is 3500 but the payment amount is updated as 3000.  There was no balance in Unapplied amount also.  There was no open amount either in Receipt Header (F03B13) or Open amount updated in Customer Ledger (F03B11).  We were able to find the difference only from the F03B14 table.  when we calculated the shortage came to 2000.

Another thing we noted in F0911, the entry had been created only for $ 8000 and not $ 10000.  therefore, there is difference between F03b13. F03b11 Vs F0911.
