Why can't I see all invoices on Project Transactions?
You can see the invoices of the projects that you manage on the Projects > Transactions screen. This is controlled by a security permission 'Allow Access to Data of All Employees'. It seems that this permission is not enabled for you and so it prevents you from seeing all the invoices. To see all the invoices, you must have this security permission enabled by the Owner/Admin of your CORE account.
