Sale Amendment Module
#####################
The sale amendment module allows you to change sales that are being processed
and keep track of the changes.
An amendment is composed of action lines which can:
* Recompute taxes (if the customer tax rules or product taxes have changed).
* Change the payment term
* Change parties and addresses
* Change the warehouse
* Change a sale line:
* the product (for one with the same UoM category)
* the quantity and unit of measure
* the unit price
* the description
When the amendment is validated the sale is updated and given a new revision.
Generated documents (like shipments and invoices) that are still in a draft
state are replaced with new ones based on the new values.
