Pivot multiple month columns

I have a dataset which comes across normalized with 3 different months under month column. 

 

This needs to be pivoted has columns in a table for users.

 

Issue is the 3 months changes. 

 

I cannot use matrix for end users as there are too many other columns needed.

 

I tried pivoting the  in Power Query but since the column names are different the reports fail. 

 

I tried pivoting the source and bring in the data and auto-renaming the columns using the actual month names in another table. Again this is failing here as its being seen as a new column.

 

Any one has another suggestion?

 

Thanks!

    Hi acbg,

     

    Based on my test, you should rebulid your visual here. As I can reproduce your issue here. Or if you just add rows in your data source, then everything should go well.

    Hi acbg,

     

    I made a sample as below. We can Pivot the Month column based on the sales column.

     

     

    Here is the M code in power query for your reference.

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8s3PK8kwVNJRAuFEpVgdJCEjIE5CFTIG4mRUIRMgTkEIgTSZopoFEjJDNcsIamMyqpARqlnGUBsTUYVMUM0yxrTRGNNGY4TrYwE=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [Month = _t, sales = _t, users = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Month", type text}, {"sales", Int64.Type}}),
    #"Pivoted Column" = Table.Pivot(#"Changed Type", List.Distinct(#"Changed Type"[Month]), "Month", "sales", List.Sum)
in
    #"Pivoted Column"

    For more details, please check the pbix as attached. If it doesn't meet your requirement, kindly share you sample data to me.

      if we use the actual month name instead of Month 1 then it does not work.

       

      For example: Instead of Month 1,Month 2, Month 3. Use Jan, Feb and Mar.

       

      Then re-name the months as Apr, May, Jun. in the dataset and reimport it. M code works when we pivot it with new column names as Apr, May and Jun.

       

      But the end graph/table in Power BI do not auto-recognize the change in column names from Jan, Feb and Mar to Apr,May, Jun.

       

      It errors out as its unable to find Jan, Feb and Mar columns.

      Hi v-frfei-msft, 

       

      Is it possible to achieve the table shown in the first image with a dataset similar to the table in the second image?
