Hi Armando,

The option to delete the line item products within an order transaction is currently not supported, only the ability to delete the entire order. But I do agree it would be a useful feature to add. If you would like a quote for us to add this feature enhancement please send an email to sales@smith-consulting.com with a link to the forum post.

In regards to the price adjustment communicating with Auth.net after a purchase is updated, the only time the Manage Order Details will communicate back with Auth.net is when a credit card is settled when processed using the Authorize Only Payment Method so you would be able to change the amount before the transaction is settled/closed.

How do you have your Payment Methods configured?

Thanks,
