Sum values based on list of lists with column names

Anonymous — Fri, 01 Sep 2023 16:14:16 GMT

Hi,

I have a set of lists and each one has categorized ColumnNames.

I'm summing the values of each category step by step on PowerQuery, but it's taking a life time, even though my dataset isn't that big.

This is the formula I'm using
= Table.AddColumn(#"Previous Step name", "Total New Column", each List.Sum(Record.FieldValues(Record.SelectFields(_, List with ColumnNames))), type number)

I thought of having a list of lists and change the Column name and the List with ColumnNames dynamically, but I have no idea if I can do it and how to do it.

Each list would require its own Total column.

Start Table

Date	ColA	ColB	ColC	ColD	ColE
01/09/2023	1	2	null	null	3
02/09/2023	1	null	3	null	2
03/09/2023	null	3	2	1	1

listA = {ColA, ColC}
listB = {ColB}

listC = {ColD, ColE}

Result Table:

Date	ColA	ColB	ColC	ColD	ColE	Total listA	Total listB	Total listC
01/09/2023	1	2	null	null	3	1	2	3
02/09/2023	1	null	3	null	2	4	0	2
03/09/2023	null	3	2	1	1	3	3	2

Could someone help me?

Thank you

Hi, Anonymous

You can try the following methods.

In the Power Query-Transform-Unpivot Other Column:

In the Power BI Desktop:

Measure:

Total listA = CALCULATE(SUM('Table'[Value]),FILTER(ALL('Table'),[Attribute] in {"ColA", "ColC"}&&[Date]=SELECTEDVALUE('Table'[Date])))+0

Total listB = CALCULATE(SUM('Table'[Value]),FILTER(ALL('Table'),[Attribute] in {"ColB"}&&[Date]=SELECTEDVALUE('Table'[Date])))+0

Total listC = CALCULATE(SUM('Table'[Value]),FILTER(ALL('Table'),[Attribute] in {"ColD", "ColE"}&&[Date]=SELECTEDVALUE('Table'[Date])))+0

Is this the result you expect?
