Hi Samuel,

The reason why the Reference field is not editable is because it is used as an Index within Historical Orders, and also for lookup to determine if a reference number was duplicated. Editing this value would likely cause data integrity errors.

Our goal with the ability to edit OE invoices and credit notes is to allow editing only those fields that will not affect accounting (such as amounts or values linked to the GL department), reporting (such as salespersons, for commission) and integrity-based values (such as reference or document number).
