Hi Anonymous , Can you test if you append a query and its copy (duplicate the query), will they be combined successfully?

    Hello v-jingzhang, I duplicated Query 1 and tried to append it with the original Query 1, and still got the error: Expression.Error: Evaluation resulted in a stack overflow and cannot continue.

    I tried this by duplicating Query 2, and got the same result.

      I just exported the two queries into a CSV file and then loaded those CSV files into my PowerBI and appended them. They appended correctly in seconds. This points me to think it is an issue with importing them from Kusto. Do you know any limitations of appending data from Kusto?

        There is a known issue about appending data from Kusto in internal DB (ICM: 219724212) but hasn't been fixed. I will update here if there is any progress about it.

         

        Currently if you can use other data sources as alternatives? Or append them at the DB side first and then import into Power BI?
