I have a Sales Charge type with 1% charge amount which is attached to the customer. Therefore it is automatically picked by the customer orders as well.
This sales charge type is used as a Sales Charge for processing the order.
But during a partial delivery, full customer order charge is getting invoiced to the customer not for the relevant delivered amount.
Customer is complaining that we are over charging the customer in some instances due to this.
Therefore I need to Invoice the correct charge amount in partial deliveries. Also, I need the charge to get automatically picked by the order in customer order creation as well (similar to the current process).
I tried Unit Charges on the Sales Charge Type, but when its enabled I can not attach the charge to a customer.
