We have a unique scenario that we are unsure how to handle. We will have a third party that will be handing the billiing and payments for a customer. They wil be transmitting a remmitance file that can have both positive and negative amounts. This is their way of making billiing adjustments. Has anyone ever had this scenaro before? we are unsure how to handle this, either by config or ABAP. Any assistance/adivce would be helpful.
