Hi Friends!

I have a problem that I cannot solve. I have a procedure that takes
two input parameters, both represent amount of money according to one
order.
One of them represents the full amount, the other represents the
currently paid amount of money. I have to create invoice from the
orderitems based on the two input parameters. The method would be the
following: I create a quotient from the input parameters and each
item's gross value will be multiplied with this quotient. In this
case, summing the amount of multiplied values would be equal to the
currently paid amount. But this is not true. Here is the procedure.
Sorry for the hungarian naming, but the method would be seen from this
code snippet. How can I achieve, that summing the BRUTTO_ERTEK_ARANYOS
field would be equal to the input parameter BEF_OSSZEG?

The full amount of money is the TELJES_OSSZEG, the currently paid is
BEF_OSSZEG.
