Charge a Sales Order greater on its Authorized Amount

Users can only bill/charge a pre-authorized sales order for:
1. the amount less than the original authorization
2. the amount equal to the original authorization

If a user will attempt to bill a pre-authorized sales order for the amount greater than the original authorization, the user will get a notice like this:

-- "Invalid Transaction Amount. Correct settlement amount to be less than or equal to the original authorization."

Notes: There is already an enhancement request filed to allow pre-authorized sales orders to charge greater than its authorized amount. This is log under:
- Enhancement 24749 - Payment Processing > Allow re-authorization of un-charged sales orders to account for expiration or amount changes on the order.
