MYOB item sales reports default to the description stored in your inventory list rather than the customised line-item text entered directly onto individual invoices.
This occurs due to the database structure. MYOB links item sales reports to the original item profile (Item Information) rather than the transactional line text of a specific sale. Furthermore, the reporting engine currently lacks a column to swap or override this default description with the customised invoice line description if you edit the text during data entry.
It’s high time this shortcoming was rectified to save us all the hassle of manually exporting the fields into a new database and running tailored reports.
