Understand how multiple discounts and coupons being used per transaction

I have an issue in my system.

We have multiple store coupons running effectively at the same time. I have 3 coupons: CP1 ~ discount 10$, CP2~ discount 20$, CP3 ~ discount 20$

When a customer made a sale transaction and apply all 3 coupons, in the Trans coupon I see 3 rows:

  • CP1 with used quantity = 1, used value = 50$

  • CP2 with used quantity = 1, used value = 0

  • CP3 with used quantity = 1, used value = 50$

So in total, this sale transaction used 100$ value of coupons. I don’t know why this occur.

Could someone please help me to explain this?

A broader question is, how is discount priorities (A/B/C/D/E/F/G) being used in the calculation? I’m suspecting this issue is related to that, as our Retail Setup is set with all values to SUM

Many thanks

hoanguyen711, I think you use AddOn, right? What is the version of NAV, Localization, etc.

P.S. From my small opinion the appling is not correct and Coupons is “like” a payment method and you need to mix it with quantity&price&total amount of sales items

I use NAV 2015. As an user, I’m not sure we use add on or not. But from what I see, seems not

You have to contact the company where you bought the add-on, this is not a standard module so its only possible to help you if a another user also have the module.

Can any help me to explain how the sequence is being used in NAV in this link: http://help.lsnav.lsretail.com/Content/LS%20Retail/Sales%20and%20Marketing/Prices%20and%20Offers/Price%20Overview.htm

Thanks

If you don’t understand the above picture or believe that it is wrong then - Let me repeat myself:
