What is relationship ambiguity?

< 1 min read

Relationship ambiguity happens when there are multiple filter paths between two tables.
This creates confusion in how filter context flows.
Power BI may not know which path to use for filtering.
For example, if Sales connects to Date table through two different relationships, ambiguity occurs.
In one project, this caused incorrect totals in time-based reports.
We resolved it by keeping one relationship active and others inactive.
Then we used USERELATIONSHIP in DAX when needed.
Avoiding ambiguous relationships ensures accurate and predictable calculations.
