DAX Full Course in Tamil | Section 06 - DAX Logical Functions | For Power BI Developers & BI Analyst

Want your DAX measures to think for themselves? That's exactly what
Logical Functions do.

In Part 6 of our DAX Full Course, we cover DAX Logical Functions —
the functions that let you add conditions, handle errors, and control
what your measures return based on the data. Once you know these,
your reports stop being static and start being dynamic.

WHAT'S COVERED
✅ AND – Return true only when all conditions match
✅ OR – Return true when any condition matches
✅ NOT – Reverse a logical condition
✅ IF – Return different results based on a condition
✅ TRUE & FALSE – Work with boolean values directly in DAX
✅ IFEAGER – A faster alternative to IF in certain scenarios
✅ IFERROR – Catch and handle errors in your formulas
✅ COALESCE – Return the first non-blank value in a list
✅ SWITCH with Exact Match – Replace nested IFs with cleaner logic
✅ SWITCH with Numerical Comparison – Handle ranges and conditions elegantly
