Multiple Flags for same Reference Number

Hi,

 

I have three flags being Blank, Provisional and Final attached to the same reference number. The reference number can be at any three stages of coding. If the reference number has the status Final there will be two other lines one for Blank and the other for Provisional. I only want to extract the Final line of coding for the reference number and ignore Blank and Provisional. 

 

I can not just filter on Final as some of the reference numbers might only be at the Blank stage of coding or Blank and Provisional. I want to extract only the reference number applicable to the lines stage of coding. 

 

Any help would be greatly appreciated. I am assuming this problem can be solved using DAX or potentially in Power Query. 

 

Thanks

    Hi Lachlanpap ,


    If I understand correctly, blank, provisional and final are sequential. I'm assuming the raw data looks like this;

    PowerQuery M:

     

    let
    Source = Table,
    #"Grouped Rows" = Table.Group(Source, {"reference number"}, {{"Data", each Table.LastN(_, 1)}}),
    #"Expanded Data" = Table.ExpandTableColumn(#"Grouped Rows", "Data", {"flags"}, {"flags"})
in
    #"Expanded Data"

     

     

    Dax:

    first create a new enter table:

    then relationship:

    then please create a new measure:

     

    Measure = 
VAR __cur_sort =  CALCULATE( MAX('DimFlag'[FlagSort]), CROSSFILTER('Table'[flags],'DimFlag'[flags],Both))
VAR __max_sort = CALCULATE( MAX('DimFlag'[FlagSort]), CROSSFILTER('Table'[flags],'DimFlag'[flags],Both) ,ALLEXCEPT('Table','Table'[reference number]),VALUES('Table'[reference number]))
VAR __result = IF( __cur_sort = __max_sort, 1)
RETURN
__result

     

    and use it as table visual's filter:

    Hi,

     

    Try creating a calculated column like this for example:

    IsFinal =
    VAR CurrentRefNumber = 'YourTable'[ReferenceNumber]
    VAR HasFinal =
    CALCULATE(
    COUNTROWS('YourTable'),
    'YourTable'[ReferenceNumber] = CurrentRefNumber,
    'YourTable'[Flag] = "Final"
    ) > 0
    RETURN
    IF(
    HasFinal,
    IF(
    'YourTable'[Flag] = "Final",
    TRUE(),
    FALSE()
    ),
    FALSE()
    )

    This column will return TRUE if the reference number has a "Final" status and FALSE otherwise.

     

    Now, you can use this calculated column to filter your data in your visuals.

     

     

    Or a measure like this: 

     

    FinalFlagMeasure =
    IF(
    COUNTROWS(
    FILTER(
    'YourTable',
    'YourTable'[Flag] = "Final" &&
    'YourTable'[ReferenceNumber] = MAX('YourTable'[ReferenceNumber])
    )
    ) > 0,
    1,
    0
    )

    This measure returns 1 if the reference number has a "Final" status and 0 otherwise.

      Thanks for your reply Shravan133. I ended up using option 2 from Gao above. I appreciate your response regardless 👍

      Wow, thank you very much. I used option 2 and it worked perfectly. I am now going to study the syntax in the measure. Really appreciate your help 😀
