We are having an issue with how GA 360 is reporting revenue when a line level discount is applied to an order. The example shared in a support ticket shows how a basic Magento store setup is reflecting the problem, so the bug is built in to the out-of-the-box instance of Magento Commerce. In our site's case, we have a more customized Cart setup but the problem is the same. As a result, GA is reflecting all of our Revenue reporting incorrectly.
It doesn't appear that I can attach a file here, so a more detailed explanation is as follows. When a customer uses a coupon which applies a discount to 1 of say 3 products in their cart, the GA purchase event records the product price to be the original price. This should be recording the updated, discounted price. We are able to confirm that this discounted price is available in the "Row Total" Magento field. So the data is there for the taking. Our request is that Magento use the Row Total amount in the corresponding GA events for Product Price.
Business Impact: all of our discount revenue tracking on products is wildly different. This impacts our ability to read the success of campaigns and requires a great deal of manual effort to adjust for the error. Please correct!!!
