Getting a max step from a group

Hi All

 

I have what I think could be a fairly simply problem to solve but I have been going around and around in circles to try to get the answer and now I'm just stuck or not understanding why this would not work.

I have a table below and I want to identify with a 1 which step is the max step in the GROUP, the unique or grouped item is the DocNumber and the group has several steps, all I am trying to do is to add an indicator to say the highest step number I have tried some what I thought would work calculation but it always ends up the same way 😞

MaxStepNo =
MAXX(
    FILTER(
        'Document Steps',
        'Document Steps'[DocNumber] = EARLIER( 'Document Steps'[DocNumber] )
    ),
    'Document Steps'[StepNo]
)

Thanks to the great efforts by MS engineers to simplify syntax of DAX! Most beginners are SUCCESSFULLY MISLED to think that they could easily master DAX; but it turns out that the intricacy of the most frequently used RANKX() is still way beyond their comprehension!

DAX is simple, but NOT EASY!

ok thank you for this so that produced the last step correctly as a number in the column

I then did a 

IF(Document Steps [MaxStep] = DocumentSteps[StepNo],1,0)

Which has given me a column I can use going foward. Thanks for all your help

MaxStepNo = 
VAR _current_doc = 'Document Steps'[DocNumber]
RETURN
CALCULATE(
    MAX('Document Steps'[StepNo]),
    REMOVEFILTERS('Document Steps'),
    'Document Steps'[DocNumber] = _current_doc
)

@Greg888 Very strange! Did you change something in what I sent you? I see in your measure you want to return 1 or 0. Did you wrap my measure with additional logic for that?

@Greg888 the two measures give the same result...
How did the 1st one didn't work and 2nd did..?
(In my sample data the Doc number is group id and the step is Value for ID. I just used it on somethong that was open on my pc from another question)
