Looking Up with RELATED

Part of the Power BI Basics section of Coddy's Power BI journey. Lesson 24 of 28.

A Sales column cannot read Products[UnitCost] directly: which product?

RELATED follows the relationship to the matching row and brings back its value.

Cost = Sales[Quantity] * RELATED(Products[UnitCost])

It works from Sales towards a lookup table, which has one row per key.
