Paypal Adaptive issue with Coupons

-- HikaShop version -- : 2.3.5
-- Joomla version -- : 3.3.6
-- Error-message(debug-mod must be tuned on) -- : The amount for the primary receiver must be greater than or equal to the total of other chained receiver amounts

We have a customer who we have issued a coupon code for, and when they attempt payment they get the error above. I have duplicated this issue on our sandbox site. The coupon code is for $10.85 CAD. Paypal adaptive is configured for chained payments. With no coupon code the primary receiver receives 10.75 and the secondary receives 10.75.

Please let me know if there is any additional info you need.

Thanks,

Steve

Hikamarket Multivendor 1.5.1
Here's the screenshot of the coupon code in use:

Also, the product and the coupon are both assigned to the same vendor, who is the secondary receiver.

Hi Jerome,

I just upgraded to 1.6.0 on my sandbox site and the issue is still there. I deleted the old coupon and created a new one, and cleared and reloaded the cart to be sure that nothing would be carried over from the prior version. Please advise.

Thanks,
Steve

Setting the target vendor to "yes" corrects the problem.

To answer your question, vendor 3 created the coupon from the front end so the coupon defaults to vendor 3 as the target. Also, the product the customer is purchasing was created by vendor 3 as well.

It is possible to log into the back end and change the target to "yes", however, I would prefer that the process would be automated and the vendor could create and manage their own coupons from the front end.

The vendor is using the coupon to provide store credits to specific customers for returned items. Is there another way to achieve this?

Hi Jerome,

Another observation; with the coupon set to target vendor "yes", it is likely that the coupon would be applied to products owned by the main vendor (or possibly other vendors as well?) This would defeat the purpose of the multi-vendor/paypal adaptive setup since the goal is to automate the division of payment for products for multiple vendors while presenting a single unified front end for the customer.

More specifically, if vendor 3 receives a returned product and issues a store credit, it should only be vendor 3's products to which the credit could be applied. With our store configuration, the customer cannot differentiate which vendor owns any specific product.

Hi Jerome,

I did the same test and had the coupon indicated as invalid, but only when the cart contained no items from vendor 3. The issue is when there are items from the main vendor and vendor 3 mixed, then the coupon goes through. We just had this happen on our live site, where both items together exceed the coupon amount and each item individually was less than the coupon. In this case, it appears that the excess negative amount from the vendor 3 item was deducted from the main vendor item in the cart.

I have to do an assessment because the numbers aren't exactly lining up the way I would expect, so I want to figure out where the money was actually distributed versus what the invoices are indicating. I'll post as soon as I have time to crunch the numbers.
