DAX Measure Returning Incorrect Results
Hello,
I’m facing an issue with a DAX formula in Power BI. The results are not matching the expected output, even though the relationships and filters seem correct.
Any suggestions would be appreciated. Thank you!
Check Filter Context:
Many incorrect results come from the measure being evaluated in a different filter context than expected.
Use CALCULATE() with ALL() or REMOVEFILTERS() carefully.
Verify Relationships:
Make sure table relationships are active.
For many-to-many relationships, consider using TREATAS() or adjusting your model.
Use DAX Debugging Tools:
Install DAXDebugOutput or use EVALUATEANDLOG() to see where the results differ.
Print intermediate variable values inside your measure.
Provide Sample Data:
Create a small, clear dataset showing actual vs expected results. This helps isolate the issue quickly.
Check Common Patterns:
Ensure CALCULATE() with ALL() or REMOVEFILTERS() isn’t removing filters unintentionally.
Review fields in rows, columns, or slicers that might affect results.
Try these solutions and let me know if you need further clarification

Rufyda Rahma | MIEInstall DAXDebugOutput, and familiarize yourself with the EVALUATEANDLOG function. That will help you to identify where in your measure the results are not what you expected.
Please provide sample data that covers your issue or question completely, in a usable format (not as a screenshot).
Do not include sensitive information. Do not include anything that is unrelated to the issue or question.
Please show the expected outcome based on the sample data you provided.

If you share (1) the measure code, (2) what result you expected vs what you get, and (3) which fields are on the visual (rows/columns/slicers), people can pinpoint it quickly. A quick screenshot of the model relationships also helps.
Most “incorrect result” cases end up being one of these: the measure is evaluated in a different filter context than you think (missing/extra filters), an inactive relationship, many-to-many ambiguity, or a CALCULATE/ALL removing filters unexpectedly.
Hi Remah_Ramadan ,
Can you provide more information on input/output in the form of DAX or screenshots?
Thanks and Regards,

This is too generic to debug. You need to post the actual measure, a small data sample, and what you expect vs what you get.
