What is handling blank values in models?

< 1 min read

Handling blank values in models means managing missing or null data to avoid incorrect reporting.
Blanks can affect aggregations, relationships, and DAX calculations.
For example, missing Customer IDs can break joins between fact and dimension tables.
In one project, blank Sales Amount values were converted to 0 during transformation.
For dimensions, I added an “Unknown” member to handle unmatched records.
In DAX, I used functions like ISBLANK and COALESCE to control blank behavior.
Proper handling prevents misleading totals and ensures cleaner, reliable dashboards.
