Unable to create Debit Memo, for price Correction , via REST API

Summary:

Hi Team,

We have a Use case where we want to create a Debit Memo in AP, for both Quantity and Price Hold. We want to create Debit Memo via REST API for Automated Approach.

But, upon testing, what we noticed is that,

1. We can create Debit Memo via REST API for Quantity Correction (Quantity as Negative and Unit Price is Positive), but
2. We can't create Debit Memo via REST API for Price Correction (Quantity is Positive and Unit Price is Negative), when i try to create i am getting below error,

You must enter a line amount that's 0 or higher for a matched line when the quantity is more than 0. (AP-811020)You must provide a unit price that's more than 0 for a matched line unless you're making a price correction. (AP-811024)
