SAP recommends to only change approved sales documents in exceptional cases. Once a sales document is approved, subsequent processes like deliveries and billing are triggered. Keep in mind that you will have an impact on these subsequent processes if you change any approved documents.

While SAP strongly recommends that approved sales documents should not be changed there is an Emergency fallback in that the approved sales documents can be changed via Apps such as Change Sales Orders (VA02)
