Me again

I have just started using Crystal Reports and am having trouble locating data that I want to show in the report. Of particular interest is the G/L account and department distribution for vendor transactions. I have tried different files and fields but they seem to be empty. Could somebody please point me in the right direction? I would also be very interested in a cheat sheet(what's where) for all the adagio files if that exists.

Regards,

Sandra
