Problem MAXX function with string

[hanssonnor]

Hi,

I am currently working on a measure using the following table:

Number	Item	Reason Code	Status	Center
60607788	abc	0B	10	G1A30
60607788	abc	0B	20	G1G30
60607788	abc	0B	30	G1C30
60607788	abc	0B	40	G1T40
60607788	abc	0B	50	G1X50
60607788	abc	0B	60	G1S20
60607788	abc	0B	70	G1R40
60607788	abc	0B	80	G1L30
60607788	abc	0B	90	G1H40
60607789	bbc	0B	10	G1A30
60607789	bbc	0B	20	G1G30
60607789	bbc	0B	30	G1C30
60607789	bbc	0B	40	G1T40
60607789	bbc	0B	50	G1X50
60607789	bbc	0B	60	G1S20
60607789	bbc		70	G1R40
60607789	bbc		80	G1L30
60607789	bbc		90	G1H40

I am using the following measure:

Last CC = 

VAR MaxStatus = MAX('Work Order Time Transactions'[Status])
Return
MAXX(
    FILTER(
        'Work Order Time Transactions',
        MaxStatus
        && 'Work Order Time Transactions'[Reason Code] = "0B"
    ),
    'Work Order Time Transactions'[Center]
)

The measure works but does not give me the desired result. For the table above I want to know the last Center for maximum Status and reason Code 0B. In the table, the results for abc should be G1H40 since the maximum Status with reason Code 0B is 90, but the measure computes G1X50 since the string is the biggest. I found the gap in my measure but I am struggling to solve it. 

I gladly appreciate any hints to solve this issue.

Thanks & Best regards

MAXCC =
VAR maxStatus =
    CALCULATE (
        MAX ( 'Work Order Time Transactions'[Status] ),
        ALLEXCEPT (
            'Work Order Time Transactions',
            'Work Order Time Transactions'[Item]
        ),
        'Work Order Time Transactions'[Reason Code] = "0B"
    )
RETURN
    CALCULATE (
        SELECTEDVALUE ( 'Work Order Time Transactions'[Center] ),
        'Work Order Time Transactions'[Status] = maxStatus
    )

Hi Colacan,

thanks for your approach. I had to modify it though, with the Allexcept it did not work. However once I removed that filter it showed the same results.

Best regards

@hanssonnor  Hi Hanssonnor, I have noticed that extracting highest or lowest recode within categories is quite tipical problem which lots of people are facing. And Allexcept function is quite useful for those problems.

Cheers!

@hanssonnor , Try a measure like

calculate(lastnonblankvalue('Work Order Time Transactions'[Status], max('Work Order Time Transactions'[Center])),'Work Order Time Transactions'[Reason Code] = "0B")

Hi Amit,

thanks a lot,  it works 🙂

Best regards
