Table transformation

Dear all,

 

I would like to transform a table in Power BI but I don't find the way to do it. I will clarify my doubt with an example.

 

1) I load in Power BI  a table like the following:

 

Project

Recruiting amount year X

Awarded amount year X

Contracting amount year Y

Awarded amount year Y

1

A

C

E

G

2

B

D

F

H

 

2) I would like to transform it in order to obtain the following table:

 

Project

Recruitment statusYear

Amount

1

Recruiting

X

A

1

Recruiting

Y

E

1

Awarded

X

C

1

Awarded

Y

G

2

Recruiting

X

B

2

Recruiting

Y

F

 

Could anyone shed a light?

 

Thank you very much.

This query:

 

let
    Source = Table1,
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Project"}, "Attribute", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Other Columns",{{"Attribute", "Recruitment status"}, {"Value", "Amount"}}),
    #"Inserted Text After Delimiter" = Table.AddColumn(#"Renamed Columns", "Year", each Text.AfterDelimiter([Recruitment status], " ", {0, RelativePosition.FromEnd}), type text),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Inserted Text After Delimiter", {{"Recruitment status", each Text.BeforeDelimiter(_, " ", 0), type text}}),
    #"Reordered Columns" = Table.ReorderColumns(#"Extracted Text Before Delimiter",{"Project", "Recruitment status", "Year", "Amount"})
in
    #"Reordered Columns"

Can you explain the logic?

 

E.g. how does amount E from column Contracting amount year Y end up with recruitment status Recruitment?

This query:

 

let
    Source = Table1,
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(Source, {"Project"}, "Attribute", "Value"),
    #"Renamed Columns" = Table.RenameColumns(#"Unpivoted Other Columns",{{"Attribute", "Recruitment status"}, {"Value", "Amount"}}),
    #"Inserted Text After Delimiter" = Table.AddColumn(#"Renamed Columns", "Year", each Text.AfterDelimiter([Recruitment status], " ", {0, RelativePosition.FromEnd}), type text),
    #"Extracted Text Before Delimiter" = Table.TransformColumns(#"Inserted Text After Delimiter", {{"Recruitment status", each Text.BeforeDelimiter(_, " ", 0), type text}}),
    #"Reordered Columns" = Table.ReorderColumns(#"Extracted Text Before Delimiter",{"Project", "Recruitment status", "Year", "Amount"})
in
    #"Reordered Columns"

Thank you very much Marcel.

 

It worked with the example I have given. However, I am trying to adapt the query in case there was any modification of the input table. For example, my real input table is:

 

PlaConcepteEstatCodi ActuacióLínia pressupostSubplaNom2017 moviment2017 adjudicat2017 licitació2018 moviment2018 adjudicat2018
licitació
2019 moviment2019 adjudicat2019 licitacióData extracció
Pla TecnològicLínia BaseLínia Base AM XF  H     09/10/2017
Pla TecnològicContracteAdjudicat BN Y G  I    09/10/2017

 

Therefore, the table I would like to obtain would be:

I would really appreciate if you could help me with my real example.

 

Thank you again!

 

Sorry,

 

I insert again the input table as I see it is not clear.
