M language - referencing previous step

Hi All,

 

So I'm fairly new to Power BI, and I'm wondering why (for curiousity's sake more than anything) when using the Advanced Editor function in the Edit Queries screen, that the M code for a step always references the previous step.

 

e.g. #"Removed Columns3" = Table.RemoveColumns(#"Changed Type2",{"ExitResponse"}),
Where #"Changed Type2" is was the previous step.

 

This caused me a couple of trip ups when writing steps by hand, so some understanding of why it's doing it would be great to help me write better code.

 

Thanks!

Adam

because m is a procedural langauge, therefore it creates everything in steps.  The last step is all the changes in the data to that point.





If I took the time to answer your question and I came up with a solution, please mark my post as a solution and /or give kudos freely for the effort 🙂 Thank you!
