I’m working on a Data Warehouse which, in the end, will require me to create reports based on business hours. Currently, my time dimension is granular to the hour. I’m wondering if I should be modifying my Time dimension to include a bit field for ‘business hour’ or should I be creating some sort of calculated measure for it on the analysis end? Any examples would be super magnificent?
Use a bit (or even another column) to specify whether an hour is a business hour at the time it is stored. Otherwise when you change the business hours you will become unable to reproduce historical reports.
