Subject Area Security - Unable to view data from relative subject area despite having role assigned

Summary: Subject Area Security - Unable to view data from relative subject area despite having role assigned

Content (required): I am currently attempting to troubleshoot an issue with data access for a user. The user has the delivered Accounts Payable Specialist role and is unable to see the data within some of the folders of the subject area - Payables Invoices - Transactions Real Time. From what I understand, the documentation states that this role secures access to this subject area. However, for example, if I include invoice details, the user would receive a "No Results The specified criteria didn't result in any data." message. Would anyone have any thoughts as to why this is the case? Thank you for
