tryton-modules-sale-amendment 6.0.2-1 (amd64 binary) in ubuntu oracular

 Tryton is a high-level general purpose application platform. It is the base
 of a complete business solution as well as a comprehensive health and hospital
 information system (GNUHealth).
 .
 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.
