Hi  @Anonymous ,

According to the error message, it seems that the fields in Employee table be set mismatched data type. Please check these fields which the data type be set as Numeric type. Or you can provide the screenshot of Employee table and applied codes on Employee codes in Advanced Editor, later we can make troubleshooting and give you a suitable solution. Thank you.

Thanks for your response.  Other Power BI sources also tell me that, but I'd greatly appreciate it if you could let me know if there is a way to get to the exact point of the error quickly, as step by step in the query pane doesn't show me where that error is.

@Anonymous , You need open the power query and check step by step. A column is giving an error after the type is changed to a number. All such column for which you have change type to number and at source it not number, they can give error.

Also, it can happen, that by default power query made it a number and you corrected it by making it text by adding a new step. But it need to corrected at very first step where power query made it a number
