Query from Service Pack using SummarizeColumns and add a column with Switch (Case When in SQL)

Trying to get data using this query adding Switch function similar as case when using switch but not working.

 

EVALUATE
SUMMARIZECOLUMNS (

'Geo Hierarchy'[Country],
'Prod Hierarchy'[Product Lvl 1],
'Prod Hierarchy'[Product Lvl 2],
'Prod Hierarchy'[Product Lvl 3],

SWITCH('Prod Hierarchy'[Product Lvl 7],{"Play"},"Play",
{"Run"},"Run",
"Others"
),

 

FILTER (
VALUES ( 'Geo Hierarchy'[Country] ),
'Geo Hierarchy'[Country], IN { "Latam","US"}
),
"Total Revenue", [RevUSD]
)

    juanroblesoct9 Try:

    SWITCH('Prod Hierarchy'[Product Lvl 7],"Play","Play",
    "Run","Run",
    "Others"
    ),

     

    If a measure, you may have to use an aggregation around your column, if it is a column.

      Is a column as want to replicate case when in SQL.

      The sugestion is not working.

      the error shown "A single value for column "Prod Lvl7" in table "Prod Hierarchy" cannot be determined.  This happen when a measure formula refers to a column that contains many values without specifying an aggregation such as min, max, count...

    Let me elaborate on the question, below will find an SQL and DAX intended view which is not working as the intent is to have less rows imported..

     

    SQL

    With PreTable as (

    Select
    'Geo Hierarchy'[Country],'Prod Hierarchy'[Prd Lvl 1],'Prod Hierarchy'[Prd Lvl 2],
    case when 'Prod Hierarchy'[Prd Lvl 3] like '%crawl%' then 'crawl'
    when 'Prod Hierarchy'[Prd Lvl 3] like '%walk%' then 'walk'
    when 'Prod Hierarchy'[Prd Lvl 3] like '%run%' then 'run'
    else 'Others'
    end [NewLvl3],
    SUM([TotalRev]) as [Rev]
    from ServicePack
    where 'Calendar'[Year]='2019'
    Group by
    'Geo Hierarchy'[Country],'Prod Hierarchy'[Prd Lvl 1],'Prod Hierarchy'[Prd Lvl 2],'Prod Hierarchy'[Prd Lvl 3]
    )

    Select
    'Geo Hierarchy'[Country],'Prod Hierarchy'[Prd Lvl 1],'Prod Hierarchy'[Prd Lvl 2],[NewLvl3],SUM([Rev])[Rev]
    from PreTable
    Group by
    'Geo Hierarchy'[Country],'Prod Hierarchy'[Prd Lvl 1],'Prod Hierarchy'[Prd Lvl 2],[NewLvl3]


    DAX (not working)


    EVALUATE
    SUMMARIZECOLUMNS (
    'Geo Hierarchy'[Country],'Prod Hierarchy'[Prd Lvl 1],'Prod Hierarchy'[Prd Lvl 2],
    SWITCH(SELECTEDVALUES('Prod Hierarchy'[Prd Lvl 3]),
    "crawl","crawl",
    "run","run"
    "Others"
    ),

    FILTER (
    VALUES ( 'Calendar'[Year]),
    'Calendar'[Year] IN { "2019"}
    ),
    "Rev", [TotalRev]
    )
