Transpose table

[Maghed]

Hi All,

Is it possible in Power BI "not via power query unpivot" to transform the below table to the other format

Table1

FirstName	LastName	Q1	Q2
AA	BB	1	3
CC	DD	5	7

to Table2

FirstName	LastName	Quarter	Value
AA	BB	Q1	1
CC	DD	Q2	3
AA	BB	Q1	5
CC	DD	Q2	7

Thank you

@Maghed I don;t think so, it is better to unpivot data in Power Query then you can use pivot or unpivot in desktop using matrix or table visual.

Thank you parry2k 

What about using summarize with VAR to create two tables with new additional columns "Quarter" and "Value"

Then using UNION to combine the 2 tables.

I managed to get this done and works perfect.

Not sure what will happen if the source table will get more data into it

@Maghed yes doing with DAX using summarize not a bad option but why not use power query when it has in-built function to do the job. 

Doing wiht power query will have better compression and performance in vertipaq enqine but that all depends on how big is your dataset?

Anyhow I will leave that decision with you, you have both the choices. You can do performance test to figure out what works best.

Thank you very much for detailed clarification

Franckly a colleague who is like me very new to Power BI  alreay started and built a lot with row data from Excel file..and will not be happy to start all over again by unpivoting data.

Thats why I figured out this dax approach as data set is very small
