What causes this issue?

You can only reject an order item in third-party order processing once
the purchase order item has been deleted. When you delete it, you should
also ensure that the supplier delivers the goods directly to the
customer if the order has not been rejected.
If you cannot delete the purchase order, then you should not reject the
sales order because the goods have probably reached the customer and
should then be billed. At this point, the customer can no longer reject
the order item.
