Data combination

[Guest]

Hello, Here my question,
If I have a list of 100 invoices values. and the client paid me $234,456.35.
How can I know from that list which of them were paid?
In stead of me looking and trying to make multiple combination to see which
invoices tie or reach that number. Is it a way than the computer or the
formula can tell me which of them make that number?
Example:
236
254
368
458
956
2272 is the total
The total I am looking for is 490 so the answer is 236+254. But doing this
from a list of 100 number is not as that easy.





It is not clear the question please let me know

It is actually customary for the customer to draft a reconcilliation, which
should accompany his payment, indicating which invoices he is paying. When
you start guessing which invoices are being paid, you are going to end up
with an insufferable mess, which may take months to sort out. There may for
example be 3 invoices to the amount of $3,245.65 on the customers statement.
According to your guestemates he can only be paying one of these. Which one
are you going to take as having being paid? I would suggest you get your
customer to indicate which invoices are being paid, and which ones not.
Those not being paid, should have some indication as to the reson why not!
