You are receiving the below error message when trying to publish an invoice.

Invalid or missing Project Reference.


This error will appear if you have not selected a Project code from the dropdown menu on the invoice. Please note that if you have selected a Cost code on a Purchase invoice, Sage 50 requires you to also select a Project Ref code.


To resolve this, please do the following:

  1. Unpublish the affected invoice(s).

  2. Select a Project Ref code from the dropdown menu.

  3. Republish the invoice.
