About attachment of Invoice approval workflow

Hi,

The invoice has been initiated for approval was sent to the right requester. When the requester received the approval notice,

the approver need to click on the attached link 'Approve/Reject individual lines', then approve is able to see the next screen to enable him to see the attached file.

However, the some other approvers does not have access to any of Oracle AP responsibility, then when they click on the attachment file link,

they will face an error saying 'You are insufficient privileges for current operations. Please contact your system administrator'

For example, a IT department director, who only has workflow user responsibility , he has no access to payable at all. in that case.
