Hi @Singh_10 ,
There might be some transformations in your M query that Power BI is not able to handle. If you have any complex calculations or joins in your query, try separating them out into separate tables or steps.
You can refer to the similar posts that may be helpful to you:

Hi @Singh_10 ,
What is the error message? Can you check if your last step name was RemoveDuplicates - Table? By default it is RemoveDuplicates, please keep the step name consistent in M language.
