Here is my sample table.

I am wanting to generate the fee slips for each student. SAMPLE_FEE is actually a view from a table.

What I want from the data is

       SID        LID LDATE     DESCR                             Amount
---------- ---------- --------- ------------------------- ----------
         456  18722 06-SEP-11 2 Month(s) TUITION FEE          1600
         458  18707 05-SEP-11 Arrears                                1200

         464  18418 20-AUG-11 Arrears                                 600
         464  18683 01-SEP-11 1 Month(s) TUITION FEE         1000  

         466  18696 01-SEP-11 1 Month(s) TUITION FEE           600
   
OK
I do not want
sid = 417 because it has no due amount (gtotal = 0)

But I want the following for the reasons given as well.

sid = 456 has no arrears but has not paid last two months fee (gtotal = 1600)
sid = 458 has paid some amount so arrears are there (gtotal = 1200)
sid = 464 should print two lines because it has arrears + most recent fee as well
sid = 466 has no arrears but has not paid most recent fee so far.

In simple words, report should print any arrears in one line and all the TUITION FEE after last Payment received in multiples of TUITION FEE. Once a payment is made, if it is full then do not print that sid, if it is partially paid then it should print as arrears.

Thanks for your time.

(The sample script is attached as well)
