We have a scenario where a customer places a sales order through Call centre > the order is confirmed, delivered, invoiced. After the order is invoiced the customer questions the item price that they received, for example they believe a discount was not applied. The customer paid $50 for an item, but expected to pay $45.
In some cases the business would credit the customer for that amount, if they are a big customer.
I am thinking the best way to capture these credits is using credit notes. If I look at my invoiced orders, the Credit note button is greyed out. There is a new button under Functions > Order credit. It using Infocodes in Commerce in the reason code field. When I attempt to process a credit I am getting a posting error. I cannot find any documentation about this way fo processing credits, or where to set up the required posting. Can someone please assist me?
