What does "number of invoices not canceled due to insufficient access to invoice business unit" mean

Summary:

My AP user voided a check then cancelled the invoices and received the following message. Not sure what the second line means. I can see in the system that all for invoices have been successfully canceled. Does anyone know what this line means?? "number of invoices not canceled due to insufficient access to invoice business unit" See attachments
