Hi, and welcome to the InfoPath Dev forums.
It sounds like you are not saving your "form" anywhere but instead using InfoPath to submit the data to Access, is that right? Typically I would think of using an actual form (XML saved somwhere, SharePoint, network folder etc) and when the user submits the form you could have the form e-mailed to their manager. The Manager then opens the form and authorizes the reuquest. All along the way your Access (or SQL) DB is updated with the data you need to report on.
I think it would help to understand a little bit more about your design to help make some suggestions.
