Dear Sir
Thanks for the answer by the way is there any way to slove my free item
problem .

I want to make a decison table  in excel where my client will fill in  the
item and free item list  as


Purchased ITem             No of purchase                 Free Item
No of free
==========================================================
Pen                                2
Rubber                 1
Pen                                5
Pencil                   1
Pen                               10
Pencil                   3
Pen                               12
Pencil                   4
Ink bottle                        3
Sticker                   1
Ink bottle                        5
Sticker                   2
Ink Bottle                       10
Sticker                  5


When a customer buys     19 pen then
his free item will be
4  pencil (due to first 12 pens)
5 pencil (due to remaining 5 pens)
1 rubber (due to  2 pens)

I have been trying to write the rule and fit into excel since from 1 week
but due to my limited knowledge of drl and decision tables in excel it is
taking a lot of time than writing code with lookup table and JAVA if else

Please help me to slove this riddle



Thanks
Niraj
