How do I review and audit old form data?

There are a couple of ways to do what you're asking, and it very much depends on who is doing the task of travel review.

For example as a system administrator you can look up old cases via the Admin console.

But I suspect you are looking at this from a business perspective and want HR to review the past Travel Requests.

In this case I would use the Getting Started example front end to show the information.

My process would be something like:

Init Form - Which employee would I like to look up - for example type the employee id in a text box or use a Select DDL.

Second form, show the BDO's (Business Data Objects (which are instances of a BDM)) as shown in the Init Form for the Travel Request example, obviously selected by the employee id from the Init Form above.

The thing to remember here is that BDO's persist and are always available (not archived) so you can use them all the time and for any requirement. So if your Travel Request holds all the data as required by HR then you don't need the archived process information, just the already existing BDO's
