Create a measure for prior and latest count based on last date

[giordafrancis]

qConsider the below table:

id	rag	date
101	red	01/06/2020
101	red	02/06/2020
103	red	01/06/2020
103	green	02/06/2020
103	green	05/06/2020
101	green	05/06/2020

I'm looking to create two measures:

1. one that tallies the count of all id except the latest submission date (05/06/2020 in this case)
2. another that only tallies the latest  date

Desired outcome for 1

count_prior
	red	amber	green
101	2
103	1		1

Desired outcome for 2

count_latest
	red	amber	green
101			1
103			1

Thank you in advance

Here are two expressions that should work.

Count Latest =
VAR __maxdate =
    CALCULATE ( MAX ( 'Table'[date] ), ALLSELECTED ( 'Table' ) )
RETURN
    CALCULATE ( COUNT ( 'Table'[id] ), 'Table'[date] = __maxdate )


Count Prior =
VAR __maxdate =
    CALCULATE ( MAX ( 'Table'[date] ), ALLSELECTED ( 'Table' ) )
RETURN
    CALCULATE ( COUNT ( 'Table'[id] ), 'Table'[date] < __maxdate )

If this works for you, please mark it as the solution.  Kudos are appreciated too.  Please let me know if not.
