Now refund the same invoice. When refund is processed for such an invoice having discount, the refund invoice does not account for the discounted amount, instead only the pre-discount amount gets refunded.
Following are the screen shots from QA04.
Invoice with Discount -
When the functionality of Discount with an amount (Fixed Discount under Discount Method) was being implemented, the column “discount_percentage”, “disc_acc_id”, “discount” and “discount_type” of the table “account_invoice” were not considered for the process flow of refund of the sales order.
Because of while refunding a sales order, the system could not identify if there was any discount (Fixed Discount under Discount Method) applied to the invoice.
@angshuonline I have raised a PR for this against ticket BAH-965
