Just as with payments, some times it's hard to know if your discount that you've created is applying to the correct item. Some times a configuration may have been off and not all the items received the discount that was intended. Here's an example of an invoice with a discount applied to it but to the wrong item:
In this instance, I actually wanted to apply the discount towards the registration fee, not the class. Well, as mentioned similarly with payments, we over a discount allocation screen to properly update how your discounts are being applied to an item. This can be found in the "Actions" drop down under "Reallocate Discounts":
From there, I'm brought to a new screen where I can set how the discount is allocated. I would just need to select the discount in the drop down that I'm updating. In this instance, there's only one discount to update:
Since I want the whole discount to go towards the Registration Fee, I would just need to update it as such so the full $10 is going towards that item:
A few notes on this. First off, you can only allocate up to the total amount of the discount itself. This means you cannot increase or decrease how much the discount is applying for, you're just setting how it's being split between each item. Also, if any fees are supposed to be $0, you must fill the box in as $0 for the discount to properly update.
Once done, just select "Update Discount Allocation" and you'll be brought to a screen indicating this was successful:
Afterwards, just select "Back to Invoice Detail" and we'll get to see how the discount is now being applied:
