Unable to convert M query into Native Query



We are facing dataset connection issue only on Training environment whereas reports are working fine for all the other environments. This error is also not consistent, it is appearing for some users whereas for other users this error does not appear.


Whenever few users try to login into the report they get error Unable to convert Mquery to native query error, but they can use same reports on the other environment. what can be the reason?


Here is the screenshot of error,




Only few users getting this error and others can access reports with no errors.

Need help in understanding this inconsistent behaviour.

Hi @Pravina2592 ,


Would you please try to use the latest verison of power bi desktop and republish the report to web service again.  Please check the applied steps in query editor.

For more details,  please refer to the similiar post: and
