Reviewing the order
A validated order cannot be modified. It must be revised.
Logging the order
Logging an order allows you to keep an image of the initial order. You must perform this type of archiving process before delivering the order, if it is not coming from a logged quote.
Reminder: Logging an order is only possible if the order was not a former logged quote.
From the order to be validated, go to Edit > Log the order. The order is automatically added in the orders history list.
