I do not understand why the VIEWS found in DBC are trimming DatabaseName, TableName and ColumnName to length 30 when Teradata 14 are capable of handling object names up to 127?
I think this discussion can help you:
When you do show select * from dbc.tables, you can see how it is built-up.
you have to use the V versions of the views from 14 onwards
these will show the full names...
From the manuals:
Could mean some changes to different maintenance and analytic scripts...
