Hi @poojashribanger ,
Pleae have a try.
Create a measure.
measure =
VAR _1 =
RANKX (
FILTER ( ALL ( 'table' ), 'table'[id] = SELECTEDVALUE ( 'table'[id] ) ),
CALCULATE ( MAX ( 'table'[date] ) ),
,
DESC,
DENSE
) //Sorts dates under the same id.
VAR _maxdatre =
CALCULATE (
MAX ( 'table'[datetime] ),
FILTER (
ALL ( 'table' ),
'table'[id] = SELECTEDVALUE ( 'table'[id] )
&& _1 = 1
)
)
VAR _2nd =
CALCULATE (
MAX ( 'table'[datetime] ),
FILTER (
ALL ( 'table' ),
'table'[id] = SELECTEDVALUE ( 'table'[id] )
&& _1 = 2
)
)
RETURN
( _maxdatre - _2nd ) / 2
