You may find two solutions here:

They both have some limitations, but you can bypass them or anyway use the idea. Some comments there are in Russian, so let me know if you need to read comments.

>I'm working on a reconciliation project and i'm stuck. I have a list of numbers lets say 100 numbers and I have a target amount that some permutation of these numbers adds up to. I don't know how many of them will add up to this number. I need the list of numbers that adds up to my target number. I tried writing this but my brain overworked itself. Anybody ever write something like this or have any ideas? Thanks in advance!!!

>11.31
>10.00
