Steps to Duplicate
Purchase a membership that treats the tax deductible portion from benefits as contributed membership revenue. Make sure you use a membership promotion that takes a certain amount off that membership
Go to the constituent record of the constituent that purchased the membership and click on the revenue > revenue history tab
Notice that the donation on the constituent record may be discounted by the amount of the membership promotion instead of the membership payment being discounted
Click revenue > total revenue and payments and go to the payment date of the payment
On the total revenue and payment report the membership payment and donation payment may be discounted by the amount of the membership promotion
