Clean up test payment transaction from drupal commerce site
The short answer is there is no such page. What you're attempting to build with VBO should work well, but currently there is no automatic deletion of payment transactions when orders are deleted. It's questionable whether or not we actually want that to be the default behavior. However, if you're just using VBO driven by custom rules components, you should be able to load any payment transaction referencing the order to be deleted and delete them from within the same rule. Using commerce_order_delete() will not delete payment transactions; for that you'd need commerce_payment_transaction_delete().
