1/2/22 12:30	on	1
1/4/22 16:15	off	1
1/2/22 18:15	off	1
1/5/22 12:15	on	2

Hi @dschul365 

please try

Latest On Time =
MAXX (
FILTER (
CALCULATETABLE ( 'Table', ALLEXCEPT ( 'Table', 'Table'[ID] ) ),
'Table'[Type] = "on"
),
'Table'[Date]
)

Hello @tamerj1 

Unfortunately, once applied this formula only returns blank values within the Latest On Time column. Could you explain how the ALLEXCEPT forumla is intened to work here?

@dschul365 

The CALCULATETABLE  with ALLEXCEPT should return the complete table of the current ID. This should work if Type is a column rather than a measure. Is it?

aslo please try

Latest On Time =
MAXX (
FILTER (
CALCULATETABLE ( 'Table', REMOVEFILTERS (), VALUES ( 'Table'[ID] ) ),
'Table'[Type] = "on"
),
'Table'[Date]
)
