DAX for Power BI videos | DAX for Power BI Part 3.2 - The LookupValue Function

Posted by Andrew Gould on 23 October 2021


This video explains how to use the LookupValue function in DAX. You'll learn how to lookup values between tables which don't have relationships and how to deal with items which return no matching value. You'll see how to nest LookupValue functions to search for values in a chain of tables. You'll also learn how to find values by matching on multiple columns and how to lookup values in the same table in a different column.
