Changing Sales Orders with Payment Cards 
Changing Sales Orders with Payment Cards
Purpose
The customer may want to add items to an existing sales order, or the clearing house may deny authorization. In the first case you will need to reauthorize and in the second to change the payment card plan attached to the sales order.
Once a card item has been billed, you cannot change data for the card in the payment card plan.
Features
When you raise a sales order value, the system automatically creates a new authorization to cover the difference between the old and new sales order values. The original authorization remains valid and is applied.
For example, if you add an item to a sales order, increasing the sales order value from USD 200.00 to USD 250.00, the system will execute a new authorization for USD 50.00. The first authorization for USD 200.00 remains valid and will be applied.
Process Flow
Before changing your payment card data, you can review the billing status of the cards by choosing the Settled in billing docs button at the bottom of the payment card plan. This function provides you with information on cards that have already been billed. You can use this information to change the sales order more efficiently.
The system generates a list of information including:
Card number
Expiration date
Charges
Currency
Billing documents
Authorization information
To delete a card item that has not been billed, you must first delete all of its authorizations. If the card item has already been billed, you can no longer delete it. You can, however, set the maximum amount to the amount already billed. This ensures that the system will not take the card item into account when creating new billing documents.
To add a card item, you simply enter the new card into the payment card plan. Remember to review all maximum amounts.
