What is circular dependency in data models?

< 1 min read

Circular dependency occurs when two or more objects depend on each other directly or indirectly.
In data models, this usually happens between calculated columns, measures, or relationships.
For example, Column A depends on Column B, and Column B depends on Column A.
In one project, a calculated column referenced a measure that indirectly referenced the same column.
This created a circular reference error during refresh.
Power BI cannot determine calculation order in such cases.
We resolved it by redesigning logic and moving calculations to measures.
Avoiding circular dependency ensures stable model refresh and clear dependency flow.
