- How can I prevent users from voiding sales orders if they have linked purchase orders?
- Go to File > Company > Master, and set
Restrict S/O Cancel with Uncompleted Line Item P/O Links to Yes.
This option disables the Cancel & Void button on the Sales Order when products are linked to Purchase Orders.
If you set this Company Master flag to No, then the Cancel & Void button remains enabled: when you select it, you will see a warning message about the linked purchase orders, but you will be allowed to cancel anyway.
If you have already received the product from a purchase order that was linked to the sales order, but you want to void the sales order, then you must change the Quantity Ordered on the sales order to 0, and make the order to $0. You can then void the sales order.
