Unpivot columns using dax

[Anonymous]

Hi there,

I've created a table using data from an imported table and since I've created this table using DAX, I can't manipulate it in the power query editor. I'd like to unpivot all the columns I've created, is there a way to do this using DAX?

I created my table using selectcolumns, and created 38 columns.

Thanks in advance.

Hi @Anonymous ,

A simple example. Hope this is helpful.

Table 2 =
VAR t1 =
    SELECTCOLUMNS ( 'Table', "Date", [Date], "Store", "Store1", "Value", [Store1] )
VAR t2 =
    SELECTCOLUMNS ( 'Table', "Date", [Date], "Store", "Store2", "Value", [Store2] )
VAR t3 =
    SELECTCOLUMNS ( 'Table', "Date", [Date], "Store", "Store3", "Value", [Store3] )
RETURN
    UNION ( t1, t2, t3 )

Best Regards,

Icey

@Anonymous , I would suggest to better do what you did in DAX to create that table in power query and use unpivot there.

Anyways refer dax way

Thanks for your reply. I understand that it is much easier to unpivote a large table using power query editor, however my table does not show in the editor as I've created it using the new table button.

How can I go about creating a new table so that I'm able to edit it in power query?
