When creating a new Sales Order it's very common, for example, to reference a customer's incoming purchase order number--and this is sufficiently accommodated by the Reference# field.

However, when creating a new invoice from within an existing Sales Order that has a Reference#, the Reference# is not available. Instead, the actual Sales Order number is added. This should not be the case because a sales order number should be an internal tracking number, while a reference number should be for external tracking (such as a customer's purchase order number).

It is further confusing because the Invoice template has a "Reference Field" item, but this field is also automatically tied the Sales Order number, not the Reference#.

Can we please clearly differentiate between a Sales Order Number and a Reference Number, and have them both available when creating an invoice? We can then decide whether we want either or both of these to appear in our Invoice templates.

Thanks, and keep up the great work!
