I'm saying based on account security, but it could be query based (by vendor or invoice) as well.

The major problem is that our budget managers don't need to see ALL the invoices in our system. It's a lot of extra information to filter out, especially for people who will only log in to approve expenses related to their budget.

The secondary problem is that some staff members have invoices for consulting fees, which should be confidential and not visible to all of our budget managers, making this a data security issue as well.
