+Usage
+=====

+
+On the Invoice generated from a Sales Orders, for the lines generated from the SO, the Product, Quantity and Unit Price fields should not be editable.
+
+Changing these requires deleting (or cancelling) the draft invoice, correcting the data in the source Sales Order, and then redoing the Invoice creation.
+
+Note that other columns can be edited, such as taxes or accounts, and that additional lines could be manually added and fully editable.
