How to get the the Last Contract Termination's Cause using DAX ( LAST_VALUE Over Partition in SQL)

[Anonymous]

Hi everyone,

I have this non-sorted table that is listing for each contractID all the status of this contract. 

You'll notice that a contract status can be at Terminated and then get back to "On-Going" and that the table is not sorted by year

I want to get as an output FOR EACH CONTRACT the Status Reason for the LAST time the CONTRACT STATUS have been TERMINATED. 

SO i should get this values for the ContractID 1 and 2.

ID	Last Termination Status
1	By Choice
2	Retirement

I know i can get it using SQL with something like this : 

LastTerminationStatus =  LAST_VALUE(StatusReason) OVER (PARTITION By ID ORDER By StatusDate) Where ContractStatus = "Terminated"

But i really don't know how to get it using DAX. I tried LASTNONBLANK but this fuction requires a sorted table which is not the case here

Thank your in advance for your help !!

@Anonymous here are two measures that can get you the result

Last Terminate Reason Method 1 = 
CALCULATE (
    MAX ( 'Last Terminate'[Status Reason] ),
    TOPN ( 1, FILTER ( ALLEXCEPT ( 'Last Terminate', 'Last Terminate'[Id] ), 'Last Terminate'[Contract Status] = "Terminated" ), [Status Date], DESC )
)

Last Terminate Reason Method 2 = 
VAR __table = FILTER ( ALLEXCEPT ( 'Last Terminate', 'Last Terminate'[Id] ), 'Last Terminate'[Contract Status] = "Terminated"  ) 
VAR __lastDate = CALCULATE ( MAX (  'Last Terminate'[Status Date] ), __table )
RETURN
CALCULATE (
    MAX ( 'Last Terminate'[Status Reason] ),
    __table,
    'Last Terminate'[Status Date] = __lastDate
)

Thank you very much for your answer.

The first method didn't get me the result i want. But the second one did work perfectly and is also a pretty nice method. So thank you again !! 🙂

@Anonymous , check if one of the measure can work for you

measure = calculate(lastnonblankvalue(Table[status_date], max(Table[contract_status])))

measure = calculate(lastnonblankvalue(Table[status_date], max(Table[contract_status])) allexcept(Table[ID]))

measure = calculate(max(Table[contract_status]), filter(Table,Table[status_date] = calculate(max(Table[status_date]), allexpcept(Table,table[ID]))))
