Power BI - SQL query with Case When to DAX? - powerbi

Question

I am trying to convert a below SQL query into DAX on my Power BI Report.
SQL QUERY: -
select Date
,Id
,MAX(CASE WHEN fkid = 1 then 1 else 0 end) as rflag
,MAX(CASE WHEN fkid = 128 then 1 else 0 end) as dflag
,CASE WHEN MAX(CASE WHEN fkid = 1 then 1 else 0 end) = 1 AND MAX(CASE WHEN fkid = 128 then 1 else 0 end)=1 THEN 1 ELSE 0 END AS BOTH
from table
GROUP BY Date,Id
INPUT TABLE: -
DATE ID FKID
09-07-2021 1 1
09-07-2021 1 128
09-07-2021 2 1
09-07-2021 3 128
10-07-2021 4 1
10-07-2021 4 128
10-07-2021 1 1
10-07-2021 1 128
FINAL OUTPUT :-
DATE FKID RFLAG DFLAG BOTH
09-07-2021 1 1 1 1
09-07-2021 2 1 0 0
09-07-2021 3 0 1 0
10-07-2021 1 1 1 1
10-07-2021 4 1 1 1
i have try to implement following dax query.
DAX: -
TEMTABLE =
GROUPBY(
TABLE,
TABLE[DATE],
TABLE[FKID],
"rflag", MAXX(CURRENTGROUP(),CALCULATE(TABLE,TABLE[fkID]=1),
"dflag", MAXX(CURRENTGROUP(),CALCULATE(TABLE,TABLE[fkID]=128),
"both", MAXX(MAXX([rflag])=1 AND MAXX([dflag])=1)
)

PowerQuery solution:
let
Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMrDUNTDXNTIwMlTSUYLgWB1swkYWmBJG2NUbI6k3NECSMIGrxxTGpt4Qu3q4e2IB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [DATE = _t, ID = _t, FKID = _t]),
#"Changed Type" = Table.TransformColumnTypes(Source,{{"DATE", type date}, {"ID", Int64.Type}, {"FKID", Int64.Type}}),
#"Added Custom" = Table.AddColumn(#"Changed Type", "rflag", each if [FKID] = 1 then 1 else 0),
#"Added Custom1" = Table.AddColumn(#"Added Custom", "dflag", each if [FKID] = 128 then 1 else 0),
#"Grouped Rows" = Table.Group(#"Added Custom1", {"DATE", "ID"}, {{"rflag", each List.Max([rflag]), type number}, {"dflag", each List.Max([dflag]), type number}}),
#"Added Custom2" = Table.AddColumn(#"Grouped Rows", "both", each if ( [rflag] = 1 and [dflag] = 1 ) then 1 else 0)
in
#"Added Custom2"
DAX solution:
Table 2 =
ADDCOLUMNS (
SUMMARIZE (
'Table' ,
'Table'[DATE], 'Table'[ID],
"rflag", IF ( CONTAINS ( 'Table', 'Table'[FKID] , 1 ) , 1 , 0 ),
"dflag", IF ( CONTAINS ( 'Table', 'Table'[FKID] , 128 ) , 1 , 0 )
),
"both", IF ( [dflag] = 1 && [rflag] = 1 , 1 , 0 )
)
