Is there any (openly) available documentation on EPIC clarity table relations (aside from the data dictionary, eg. table relation diagrams, data flow documentation, or docs on how certain tables ‘work’ (specifically in the area of Professional Billing))?

Have access to specific tables in EPIC clarity as well as access to the full data dictionary. However, any tables beyond the existing subset that I already have are time consuming to get access to. Thus, would be very useful if there were a way to look at table relations and find what tables were needed to generate a desired kind of report before making lengthy access requests.

Googling could not find any such docs or community forums, but would love to be proved wrong.

Thanks.
