My datawarehouse table contains only one SQL column date, but I want to be able to expand using normal levels of year / quarter / month / day.
I could manually create a new column using the Pentaho Kettle, and then create the levels one by one in the Pentaho Schema Workbench.
But this is such a common task (I think everyone who creates cubes related to sales should do this), so I'm sure Pentaho has developed something for this in a matter of seconds. What is the recommended way to do this?
