Power Query Calculation Help

Hi Guys,

 

need some help with Power Query M Code as im new to it.

 

I want to make some columns and it has to be in Power Query as i need to ammend this into another table.

 

I want to make columns using these DAX formulas but alter them to M Code:

REV - VAL = 
VAR
REV = CALCULATE(SUM('Table1'[Value]), FILTER('Table1', 'Table1'[Name] = "Rev"))

VAR
VAL = CALCULATE(SUM('Table1'[Value]), FILTER('Table1', 'Table1'[Name] = "Val"))

Return
+REV - Direct

 

Value1 = [REV - VAL] / CALCULATE(SUM('Table1'[Value]), FILTER('Table1', 'Table1'[Name] = "Name1"))

 

Value2 = [Value1] - CALCULATE(SUM('Table1'[Value]), FILTER('Table1', 'Table1'[Name] = "Name2"))

 

How can i replicate these measures into M Code?

Hi @paulfink ,'

 

I have built a simply data sample with your DAX code:

data sample with DAX.PNG

 

Please use the below codes(List.Sum function) to create Custom columns:

 

Rev=let _item = [Name] in List.Sum(Table.SelectRows(#"Changed Type", each [Name] = "Rev")[Value])
Val= let _item = [Name] in List.Sum(Table.SelectRows(#"Rev", each [Name] = "Val")[Value])

 

...

Sum for Rev.PNG

 

After doing all sum for each Name, the table will be like this:

All sum for each name.PNG

Then:

add custom columns.PNG

The final output is shown below:
