Regarding the Discount condition type in sales order

Hi All

I have 3 key combinations in my Discount Condition Type. I have maintained records at all the 3 key combinations and all the records are relevant for a sales. In my sales order all the relevant records (all 3 records) getting displayed, but for calculation all the three discounts are considered. I do not want use exclusive concept in access sequence.

But when i use the same access sequence for Base Price, it is behaving deferrently, where whatever record is found at the last is getting considered for calculation.

Please give your valuable comments.

Your inputs are appreciated.

Thanks and Regards
