Change a sales order with advance payment

You can still change an added sales order with advance payment for which an invoice has already been generated.

After generating the invoice, you can still change the line (quantity, price) or add lines with articles or text in the sales order.
You can no longer change the following parts of the sales order: the invoice discount, the order date (the prices are determined based on the order date so after the invoicing you can no longer change it), and the packaging addition or change.

If you change something that changes the order amount, a correction invoice follows automatically. Furthermore, the check box in the order header is automatically selected.

To change a sales order with advance payment:

1. Go to: Order Management / Sales process / Sales order.
2. Open the properties of the sales order you want to change.
3. Select the entry layout.
4. Click on: OK. 
5. Change the line (quantity, price) or add new lines.
6. Go to the tab: Pay in advance.

   If the order amount has changed, the Correction invoice required check box is now selected.

7. Complete the order. in the usual way.
8. If required, generate the packing slip and report it as ready.
9. Complete the sales order, for instance, by using the Complete action.

In the case of advance payment, changes in a sales order and/or packing slip are included in a correction invoice. A correction invoice must be generated manually. You can check if a correction invoice is required in the order properties.

1. If desired, view the sales order to see if a correction invoice is necessary.
2. Generate the correction invoice after you have created one or more packing slips.
