Purchase Amendment Module ######################### The purchase amendment module allows you to change purchases that are being processed and keep track of the changes. An amendment is composed of action lines which can: * Recompute taxes (if the supplier tax rules or product taxes have changed) * Change the payment term * Change the party and the address * Change the warehouse * Change a purchase 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 purchase is updated and given a new revision. Generated documents (like moves and invoices) that are still in a draft state are replaced with new ones based on the new values.
