How can I consolidate rows?

[Anonymous]

Hello

I have that data:

ID	Header1	Header2
ID1	4	9
ID1	7	4
ID2	2	8
ID2	6	3

How can I consolidate the rows by ID and take the maximum of column2 and the maximum of column3?

It should look like:

ID	Header1	Header2
ID1	7	9
ID2	6	8

7 = max of 4 and 7

9 = max of 9 and 4 etc

Thanks!

Hi, @Anonymous 

Based on your description, you may create two measures as below.

Header1 Measure = 
var _id = SELECTEDVALUE('Table'[ID])
return
CALCULATE(
    MAX('Table'[Header1]),
    FILTER(
        ALLSELECTED('Table'),
        'Table'[ID] = _id
    )
)
Header2 Measure = 
var _id = SELECTEDVALUE('Table'[ID])
return
CALCULATE(
    MAX('Table'[Header2]),
    FILTER(
        ALLSELECTED('Table'),
        'Table'[ID] = _id
    )
)

Result:

@Anonymous , You can also try new measures like

Header1= sumx(summarize(Table,Table[ID],"_1",max(Table[Header1])),[_1])
Header2= sumx(summarize(Table,Table[ID],"_1",max(Table[Header2])),[_1])

Hi @Anonymous 

I've completed this in Power Query. Paste the following code into a blank query using Advanced Editor to follow my steps:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8nQxVNJRMgFiS6VYHRjfHCwG4RsB2SBsgcQ3A2JjpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, Header1 = _t, Header2 = _t]),
    groupID = Table.Group(Source, {"ID"}, {{"data", each _, type table [ID=text, Header1=text, Header2=text]}}),
    addMaxHeader1 = Table.AddColumn(groupID, "maxHeader1", each Table.Max([data], "Header1")),
    addMaxHeader2 = Table.AddColumn(addMaxHeader1, "maxHeader2", each Table.Max([data], "Header2")),
    expandMaxHeader1 = Table.ExpandRecordColumn(addMaxHeader2, "maxHeader1", {"Header1"}, {"Header1"}),
    expandMaxHeader2 = Table.ExpandRecordColumn(expandMaxHeader1, "maxHeader2", {"Header2"}, {"Header2"}),
    remDataCol = Table.RemoveColumns(expandMaxHeader2,{"data"}),
    chgAllTypes = Table.TransformColumnTypes(remDataCol,{{"Header1", Int64.Type}, {"Header2", Int64.Type}})
in
    chgAllTypes

I get the following output:

Hi @BA_Pete ,

Great solution but using the advance features of the grouping this is made autmatically by Power Query.

:D:D

Hi @MFelix 

You're right, I may have overcomplicated it a bit!   😄

Hi @Anonymous ,

If you wnat to redo your table you need to use the Query Editor and group by ID and then MAX for both columns:

check the code for the query editor:

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45W8nQxVNJRMgFiS6VYHRjfHCwG4RsB2SBsgcQ3A2JjpdhYAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type text) meta [Serialized.Text = true]) in type table [ID = _t, Header1 = _t, Header2 = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", type text}, {"Header1", Int64.Type}, {"Header2", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"ID"}, {{"Header1", each List.Max([Header1]), type number}, {"Header2", each List.Max([Header2]), type number}})
in
    #"Grouped Rows"

If want on the visualization you need to make a table visualization and then select the maximum values for each of the columns.
