Sounds like you're probably aiming for a virtual list.
Here's a decent roundup of how to implement it:
Basically you need to temporarily combine your two tables into one, then the body part of your "virtual" table can read out both time keeping and expense records in a single list view.
Another way to do it would be to use FileMaker's "append to PDF" functionality, appending the expense output to the time keeping output. This method doesn't give you control of page breaks very well though, so even on short reports you would end up with at least two pages.
Thank you for your reply. This is something I definitely will look into. Had a quick glance over and need to red into this in more depth to understand. But it does seem to be a solution to what I was looking for and could be more useful in more ways than one.
Appreciate it and thank you again.
