Hello,
I would like to know if it's posible to do an acumulative sum in rows with power query, for example:
I've a mother table that give me how many incidences have the client per day and the Acumulative Sum Table that gives the acumulative sum per day.
It's posbile to do this in power query or it's better to do it in Power BI?
Hope you can give the solution.
Best regards.

Hi , @diegoa2f
According to your description, you want to "do an acumulative sum in rows with power query".
Here are the steps you can refer to :
(1)This is my test data:
(2)You can put this M code in the "Advanced Editor" to refer to :
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("bY7LCUAhDAR7ydmD+RjtJdh/GyYSH/LwMLAkw7JmgMTSoEB10CGHM1eYxSAE7debMgeylTDGdT0l9BnaG7OwPCpwyyHFFh2aa+jnujMX", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Installation = _t, #"1/1/2023" = _t, #"2/1/2023" = _t, #"3/1/2023" = _t, #"4/1/2023" = _t, #"5/1/2023" = _t, #"6/1/2023" = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"Installation", Int64.Type}, {"1/1/2023", Int64.Type}, {"2/1/2023", Int64.Type}, {"3/1/2023", Int64.Type}, {"4/1/2023", Int64.Type}, {"5/1/2023", Int64.Type}, {"6/1/2023", Int64.Type}}),
#"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Changed Type", {"Installation"}, "Attribute", "Value"),
#"Changed Type1" = Table.TransformColumnTypes(#"Unpivoted Other Columns",{{"Attribute", type date}}),
Custom1 = Table.Group(#"Changed Type1",{"Installation","Attribute"},{"test",(x)=>List.Sum(Table.SelectRows(#"Changed Type1",(y)=> y[Installation]=x[Installation]{0} and y[Attribute]<=x[Attribute]{0})[Value]) }),
#"Pivoted Column" = Table.Pivot(Table.TransformColumnTypes(Custom1, {{"Attribute", type text}}, "en-US"), List.Distinct(Table.TransformColumnTypes(Custom1, {{"Attribute", type text}}, "en-US")[Attribute]), "Attribute", "test", List.Max)
in
#"Pivoted Column"
Then we can get the table you need:

Hi,
Your initial step should be to use the "Unpivot Other columns" feature on the Mother table. Then create a Calendar Table. Create a relationship (Many to One and Single) from the Value column of the Mother table to the Date column of the Calendar Table. You should then be able to write measures.
