I see alot of Q/A in the community where the requirement includes a Date Tabl that I don't think one is needed and this has me confused. So I would like to state what I think is accurate and hope that this will be either confirmed or corrected.
Scenario 1: Your core table(s) have a date field that you will want to do aggregate summaries by Week/Month/Qtr/Year.
- For this no date table needs to be explicitly created nor imported because Power BI does that for you in the background. This is per video tutorial: "https://www.youtube.com/watch?v=RiHpkN0gfPM"
Scenarial 2: Your core table(s) have a Start Date and End Date (.... or something equivalent) that bracket a range of dates. Your tables do NOT have every date between the bracketed (Start and End) range as they do not exist within any core table AND you need reporting by those in-between dates. In this case you would need to create a date table that has every date that will span the first and last dates of your core table date range.
Correct?
