how do I purge unwanted sales orders?
What NAV version you use?
If you use classic, you can do it on Administration->IT Administration->Data Deletion->Sales Documents->Delete Invoiced Sales Orders... or Delete Archived Sales Order Versions...
If you use RTC, you can do it on Departments->Administration->IT Administration->Data Deletion->Sales Documents->...
Just delete the Sales Order header.
If the sales order is completed (quantity to ship and quantity to invoice are 0), you can use "data deletion" method.
If not, you must delete from the card (sales order header).
