How get the last value on a given date

Hi Anonymous 

I think you can add an index column in Power Query Editor.

My Sample:

Group all rows by DateKey column, then add an index column by custom column.

Expand all column in Custom and remove other columns.

Build a calendar table for slicer.

Calendar = CALENDARAUTO()

Then build a measure filter and Remainder measure.

Filter = IF(MAX('Table'[DatePay])<=SELECTEDVALUE('Calendar'[Date]),1,0)

Remainder = 
VAR _MaxDate = MAXX(FILTER(ALL('Table'),'Table'[Partner]=MAX('Table'[Partner])&&'Table'[DatePay]<=SELECTEDVALUE('Calendar'[Date])),'Table'[DatePay])
VAR _MaxIndex = MAXX(FILTER(ALL('Table'),'Table'[Partner]=MAX('Table'[Partner])&&'Table'[DatePay] = _MaxDate),'Table'[Rank])
RETURN
IF(HASONEVALUE('Table'[DateKey]),SUM('Table'[RemDoc]),SUMX(FILTER(ALL('Table'),'Table'[Partner]=MAX('Table'[Partner])&&'Table'[DatePay] = _MaxDate&&'Table'[Rank]=_MaxIndex),'Table'[RemDoc]))

Result is as below.
