Clearing Customer down payment for down payment amount not equal to Customer Invoice amount

Question

Dear All,
               Below process are posting Customer transaction directly via FI without SD cycle.
            Customer down payment = 102 INR
            Customer Invoice = 103 INR
While doing Customer clearing w.r.t Invoice system has cleared the down payment document but posted an open item in Customer account with clearing document number  of value Rs 102  .
Concern:-
               1) How 1 INR difference will be countered , via receipt payment from customer from bank account ?
               2) In case we have defined tolerance limit of 5% for Customer and this come to be > 1 INR ,does SAP provide clearing Customer items
                   automatically via any Standard Customer clearing process based on rule defined  ?
Pls suggest
Regards
MJ

Answer 1

Hi,
the information of the exchange rates used for down payments, is
stored in table TCURR ( exchange rates)
For the request down payment the actual exchange rate of table TCURR
or the rate of document header is taken.
When this down payment request is payed, also the exchange rate of
the actual day (TCURR) is taken.
That´s why the amount in the bank posting in local currency result
from translating the foreign currency amount at the current rate,
instead of resulting from the total of the local currency amounts
from the settled items.
