Thanks for the reply, @JasroV. Regardless of what list I pull (invoice list, transaction list by customer), the memo/description field is only pulling in data from statement descriptions. I need to reference the information filed in invoice descriptions.

See attachment for a screenshot of the invoice description and statement description boxes on an invoice. The reports I pull are only showing the information entered into the statement description, so in this case, "voided" and not the campaign information entered into the invoice description box. 

Is there a way to pull information from the invoice description box into a report? I need to compile a list of all invoices from a certain date range with the information added to the invoice description box for each.
