Hi,
I have a single table with roughly 50 columns. I need to Unpivot 26 of these columns, but doing so in the original table is going to cause problems for some measures and calculated columns I already have set up.
So the question is, can I possibly "extract" those 26 columns (plus a primary key column) to a separate table that I can then unpivot? I have seen some potential solutions using M, but nothing that fully addressed my situation.
Hoping I can do this programatically and not build out an entirely new database table to pull into PowerBI. Happy to answer any questions or provide additional context as needed. Thanks as always!

Right click on original table - Reference - This references to the last step in original table and produce a copy. Then in this, you can do your unpivoting in this new table.

Nice...once I make the copy, can I remove the columns I don't need in the new table before using Unpivot?
Whatever you do in new table will not impact the original table. Whatever is the last step result in original table, that is the starting point for new table.
The relationship is from old to new table not vice versa.
So, remove / add or do whatever you want to do will have no bearing on the original table.
