I need to know where great plains stores all the data, i mean in which tables. Let's say i am looking at a window "item maintenance options" and i want to know which table great plains stores information on this screen, how do i go about finding that out. Somebody told me to look for SDK on CD2. Couldn't find anything but DSDK which is just "what's new in V6.0 from 5.5". I am working with V6.0 currently. Any help would be appreciated.
