Here is a sample result set:

InvoiceID DueDate GroupID SubscriberID

101 1/31/12 4 22222

102 1/31/12 4 22222

103 1/15/12 5 33333

So you see the first 2 records have the same due date, same group id , and same subscriber Id and the 3rd record is completely different...

I want my final result set to be:

InvoiceID DueDate GroupID SubscriberID

102 1/31/12 4 22222

103 1/15/12 5 33333
