Filter Latest Date and Value for each Row

Question

I have a table that looks like the following:

Name	Workgroup	Active	Modified Date Time
Kyle	A	1	10/7/2018
Kyle	A	0	10/8/2018
Kyle	B	0	10/7/2018
Kyle	B	1	10/8/2018
John	B	1	10/7/2018
John	B	0	10/8/2018
John	A	0	10/7/2018
John	A	1	10/8/2018

I need the latest value for each [Workgroup] by [Name]

For example: Kyle's workgroup A was active 10/7/18, but has been de-activated on 10/8/18.

Kyle's current stats for [Workgroup] A is de-activated.

I need to then put the sum of the activations in a table that can display how many users are active in the respective workgroup.

I was able to get halfway there with a measure that filtered the max date for the active status. However, it does not work for the table.

So, can you explain the expected results from the sample data presented and to logic to arrive at that result?

Hi&nbsp;Greg_Deckler&nbsp;I need the current status for each user and their workgroup. I was able to filter for the latest modified date time for each workgroup using this measure:&nbsp;CALCULATE(SUM(&nbsp; &nbsp;'Workgroup Table'[ActivationFlag]), FILTER('Workgroup Table', 'Workgroup Table'[ActivationDateTime]=MAX('Workgroup Table'[ActivationDateTime])))&nbsp;&nbsp;

This is what the table looks like:&nbsp;I need this to only show me the most current value for of ActivationFlag by filtering ActivationDateTime for each name and each workgroup.

I think you basically have it - does it work if you use LASTNONBLANK instead of SUM in the calc?&nbsp;CALCULATE(LASTNONBLANK(Table1[Active],Table1[Active]),FILTER(Table1,MAX(Table1[Modified Date Time])=Table1[Modified Date Time]))

I'm thinking something along the lines of:
&nbsp;
Measure = 
VAR __Name = MAX('Table'[Name]
VAR __Workgroup = MAX('Table'[Workgroup])
VAR __ActivationDateTime = MAX('Table'[ActivationDateTime])
RETURN
MAXX(FILTER('Table',[Name]=__Name &amp;&amp; [Workgroup]=__Workgroup &amp;&amp; [ActivationDateTime] = __ActivationDateTime),[ActivationFlag])
