Power BI: Bidirectional filter surprises
Selecting one category changes an unrelated KPI. Trace relationship filter directions and compare the affected measure with a simpler single-direction model.
Environment and inputs: Power BI semantic models and reports; measure behavior depends on relationships, storage mode and filter context.
Failure scenario
Selecting one category changes an unrelated KPI. Confirm the cause before choosing a fix.
Evidence to collect
Trace relationship filter directions and compare the affected measure with a simpler single-direction model. Record the time, affected scope and a healthy comparison interval.
Fix the confirmed cause
Restrict bidirectional propagation to a justified path and test all dependent report interactions. Write the expected result first. Change one relevant setting at a time.
Check the result and hand over
Repeat the check for bidirectional filter surprises using the same scope and a representative interval. Check that the symptom is resolved, expected records are present and downstream results are correct. If coverage, correctness or latency worsens, restore the recorded configuration through the agreed rollback process.
Scope and precautions
Prefer read-only access and limit queries to the relevant period or dataset. This example has not been tested on your systems. Test changes in an approved environment. Keep credentials and sensitive data out of shared evidence.
