What happens if you don‚Äôt use a proper date table?

< 1 min read

Without a proper date table, time intelligence functions won’t work correctly.
Functions like YTD, MTD, and SAMEPERIODLASTYEAR return blank or wrong values.
In one report, monthly revenue couldn’t sort chronologically and showed random order.
We also couldn’t compare year-over-year sales because missing dates broke continuity.
Multiple fact tables filtered differently since each used its own date column.
Weekends and missing days caused gaps in line charts.
Fiscal calendar logic couldn’t be implemented without custom date attributes.
Performance also reduced because Power BI auto-generated hidden date tables.
After creating a proper date dimension, trends and comparisons became accurate.
