Concatenate on Duplicate

[plantew1]

Hello everyone.

I have written the measure shown below. I get the following duplicated Rank values. What I would like to do is concatenate the CIS Type Description value when a Rank is duplicated. I have tried a few measures that don't seem to work. Is there anyone who might be able to point me in the right direction? Thanks.

CIS - Rank CIS Types Current Month =
VAR _Calc=
RANKX(
ALL( 'Lookup: CI Types'[CIS Type ID] ),
SUMX(
FILTER(
ALL('Lookup: CI Types'[CIS Type Description]),
NOT('Lookup: CI Types'[CIS Type Description] ) in { "Criteria One", "Criteria Two" }
),
[CIS - Intake Count by CI Type-Subtype Current Month]
),
, DESC, Skip
)
RETURN
_Calc​

@plantew1 that's great to hear that it worked mate! Well done!

Hi @plantew1 

Can you try the below? 

CIS - Rank CIS Types with Concatenation =
VAR _Ranking = 
SUMMARIZE(
    ALL ( 'Lookup: CI Types' ) ,
    'Lookup: CI Types'[CIS Type ID] ,
    "Rank" , RANKX (
        ALL ( 'Lookup: CI Types'[CIS Type ID] ) ,
        SUMX (
            FILTER (
                ALL ( 'Lookup: CI Types'[CIS Type Description] ) ,
                NOT ( 'Lookup: CI Types'[CIS Type Description] ) IN { "Criteria One", "Criteria Two" }
            ) ,
            [CIS - Intake Count by CI Type-Subtype Current Month]
        ) ,
        , DESC , Skip
    ) ,
    "TypeDesc" , 'Lookup: CI Types'[CIS Type Description]
)

VAR _ConcatenateTypes = 
CALCULATE (
    CONCATENATEX (
        FILTER (
            _Ranking ,
            [Rank] = EARLIER ( [Rank] )
        ) ,
        [TypeDesc] , ", " ) , 
        REMOVEFILTERS ( 'Lookup: CI Types'[CIS Type ID] )
)

RETURN
IF (
    COUNTROWS (
        FILTER (
            _Ranking ,
            [Rank] = EARLIER ( [Rank] )
        )
    ) > 1 ,
    _ConcatenateTypes ,
    MAX ( 'Lookup: CI Types'[CIS Type Description] )
)

Hope this works... let me know how it goes.

Hi TheoC,

First, just wanted to thank you for taking the time to code this for me. I'm truely greatful.

I think you have managed to come extremely close.

The DAX intellisense was giving me issues (an error) on this line and the only way to get it to cooperate was to switch the CI Type Description field for the CI Type ID field. Unfortunately, this concatenates the ID field instead of the description field. I've tried hard to understand your method and am stuck to figure out how to modify it so that it's concatenating the descriptions instead of the IDs but doesn't produce an error on this line. I'm still learning, I'm afraid.

    ) ,
    "TypeDesc" , 'Lookup: CI Types'[CIS Type Description]
)

Actually, TheoC, I just figured it out. I needed to wrap the description field in MAX and now it works perfectly. Thank you so much for your time and for your help in finding a soluation.
