How to unpivot table with multiple nested columns?

Hi 

 

We have this data that needs to unpivot however it has another layer at the top. See the example below:

 

   Vendor 1  Vendor 2  Vendor 3 
Req KeyValue 1Calculated Value 1Calculated Value 2Total ValueCalculated Value 1Calculated Value 2Total ValueCalculated Value 1Calculated Value 2Total Value
R0138216616414
R022616414515
R032616515616

 

Each vendor will have columns for Calculated Value 1, Calculated Value 2 and Total Value

 

How do we do this to unpivot this?

 

I'm appreciated your help.

 

Thanks

Hi @DCSupport 

First, Promoted Headers to get the following

Rename columns by adding "Vendor 1", "Vendor 2","Vendor 3"

Then select "Req Key" and "Value 1" columns, "Unpivot other columns",

Next, Split columns by delemiter "_",

Finally, unpivot the Attribute.2 column.

You could find detailed steps in my pbix.
