Number set to Target Value

Number set to Target Value

Number set to Target Value

I have a very large dataset from which I need to create a subset of customers where their balance equals a target value...

So for example, giving the following dataset:

Customer 1 - 30
Customer 2 - 100
Customer 3 - 50
Customer 4 - 20
Customer 5 - 50

If I set my target value to 120, then I would expect the following combinations:
Customer 2 + Customer 4
Customer 3 + Customer 4 + Customer 5

Is there a proc in SAS to do this or can someone give me a bit of direction on how I should approach this?


where would we be without rhetorical questions...

RE: Number set to Target Value

It seems that it can have n number of combinations for a given target value. More to this one customer might be contributing to every possible combinations and so get dupicated.
This is very complex task to achieve. And I dont think there is any ready made PROC available for this in SAS; So Better to have more clarification on the requirement.  


RE: Number set to Target Value


thanks for the response. You're correct, this is a very complex task and I actually found this article which describes the problem a lot better. Sadly it also highlights the unlikelihood of me achieving this!


Thanks anyway,
