Help with error message - new Power Query user

[SP3007]

Hello - can anyone help with what I can be checking with the below error message please?

1. I have checked the source data - its all fine.

2. I have ran through the steps in Power Query and they all work.

It is when I Close and Load that I get this message.

Any help greatly appreciated as I don't understand the advice on other website about this error.

Thanks!

Hi @SP3007 

When you review each step in Power Query, pay attention to any steps that involve filtering, joining, or pivoting. Verify that the data in each column is being loaded correctly without error at each step.

If above check doesn't help, try exporting the connection file of the specific problematic query. Open a new blank Excel file, test if you can connect to the data source with the exported connection file. Or create a new query to connect to the same data source from scratch manually. If the connection is successful, try close&load to see if the data can be loaded without any further transformation steps. 

Best Regards,
Jing
