While that is a fine example (best one I've seen so far) of how to use Hierarchy, it's not similar to what I pretend to do.
It would be similar if it had a table with these fields: "South Zone", "AP Region", "Kadiri", "Cuddapa", "Kurnool", "Bellary", etc.
In the example "Bellary" is the data in the intersection "Row###" (a row) and "Location6" (a column).
But for what I pretend "Bellary" is not data but both Data and a Field/Column with data for each row.
The same for "South Zone", "AP Region", "Kadiri", "Cuddapa", "Kurnool", "Bellary", etc. Each is a field with lots of data.
The question is how to connect two tables, not Field-Field... but Field-Registry. As I don't think that's possible, I ask because I'm not a pro and there might be a way. If there's no way, there are other options maybe.
