Set another column to "flag" if the specific value exists on the same day

Hi,

 

I want to set the new column to "flag" if there is a word "yes" exists in another column on the same day.

 

Example:

 

Date        | Check   | Flag

1/1/21     | no        | flag

1/1/21     | no        | flag

1/1/21     | yes       | flag

1/2/21     | no        | no

1/2/21     | no        | no

1/3/21     | yes       | flag

1/3/21     | no        | flag

 

Flag column is my desired column. I know there's an easy way to achieve this but im losta bit

I have found a way to complete this;

 

New = 
VAR dateselection = Sheet1[Date]
RETURN
    IF (
        "yes"
            IN SELECTCOLUMNS (
                FILTER (
                    ALL ( Sheet1[Date], Sheet1[Check] ),
                    Sheet1[Date] = dateselection
                ),
                "yes", Sheet1[Check]
            ),
        "flag",
        "no"
    )

 let me know if there's a better solution for this. Thank you!

Hi @aidelapplicate ,

 

Here a solution in Power Query.

Here the code in Power Query M that you can paste into the advanced editor (if you do not know, how to exactly do this, please check out this quick walkthrough)

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMjIwMtQ1ACElHaW8fKVYHSLEKlOLUQWNsCjEJmaMTbMxVGEsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, Check = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Check", type text}}),
    #"Filtered Rows" = Table.SelectRows(#"Changed Type", each ([Check] = "yes")),
    #"Grouped Rows" = Table.Group(#"Filtered Rows", {"Date"}, {{"Count", each Table.RowCount(_), Int64.Type}}),
    #"Merged Queries" = Table.NestedJoin(#"Changed Type", {"Date"}, #"Grouped Rows", {"Date"}, "Grouped Rows", JoinKind.LeftOuter),
    #"Expanded Grouped Rows" = Table.ExpandTableColumn(#"Merged Queries", "Grouped Rows", {"Count"}, {"Grouped Rows.Count"}),
    #"Replace Values" = Table.ReplaceValue(#"Expanded Grouped Rows",each [Grouped Rows.Count],each if [Grouped Rows.Count] <> null then "flag" else "no",Replacer.ReplaceValue,{"Grouped Rows.Count"})

in
    #"Replace Values"

 

When you do that, all necessary steps should appear on the right. You can browse through them to understand what has been happening.

 

Let me know if this was what you were after. If you need a solution in DAX, I can look into this, too.
