Dear,
1.Order qty is 2 so,it has multiplied with 150 rs ,so you got 300 EGP.
2.ZCMD-Discount percentage is 2% then got 6 rs .
3.Under ZCMD,I am seeing 3 rs then it has multiplied with qty 2 then you got 6 EGP .In PP ,you maintained 102 to 199 for discounts so,b/w 102 to 199 ,you had only one condition type that is existed ZCMD.
If you have any doubts please let me know .
Thanks,
Naren
