Checking for Partial Row Matches in the Same Table

 

Hi Folks,

I have an table called "Client_Shipments" with the following columns: [Client_name], [Send_location], [Receive_location], [Cost], [Error_rate]. I'm trying to check if for the client_name in each row, there's a match in the same table "Client_Shipments", which has the same values for [Send_Location], [Receive_Location], but does not have the same Client_name.

 

Basically, are there other clients who've sent something from the same start and end point? The [Cost] and [Error_rate] values do not need to match, since that's what I want to compare later. I created an example table below, along with the desired output in column [Match_found?].

 

Client_nameSend_locationReceive_locationCostError_rateMatch_found?
Client_ACANJ$10001%true
Client_AAZIL$30010%true
Client_AFLDE$4005%false
Client_BMACO15003%false
Client_BMOAK$5001%false
Client_BAZIL$4005%true
Client_BCANJ$12001%true

 

Any thoughts on how to make that work? Thank you in advance.

    Hi ndeshpande 

    You could add it as a new column:

     

    Match_Found_Col =
VAR cl = [Client_name]
VAR sl = [Send_location]
VAR rl = [Receive_location]
VAR c =
    COUNTROWS (
        CALCULATETABLE (
            VALUES ( ClientOrders ),
            FILTER (
                ALL ( ClientOrders ),
                [Send_location] = sl
                    && [Receive_location] = rl
                    && [Client_name] <> cl
            )
        )
    ) + 0
RETURN
    IF ( c > 0, TRUE (), FALSE () )

     


    Or as a measure:

     

    Match_Found_Mes =
VAR cl =
    FIRSTNONBLANK ( ClientOrders[Client_name], 1 )
VAR sl =
    SELECTEDVALUE ( ClientOrders[Send_location], "123" )
VAR rl =
    SELECTEDVALUE ( ClientOrders[Receive_location], "123" )
VAR c =
    COUNTROWS (
        CALCULATETABLE (
            VALUES ( ClientOrders ),
            FILTER (
                ALL ( ClientOrders ),
                [Send_location] = sl
                    && [Receive_location] = rl
                    && [Client_name] <> cl
            )
        )
    ) + 0
RETURN
    IF ( c > 0, TRUE (), FALSE () )

     

     

    Cheers

    ndeshpande you can try following method

     

    Add new column and measure and measure will return true/false

     

    Receive and Send Column = 'Table'[Receive_location] & 'Table'[Send_location]


Is Exist Measure = 
VAR __current = VALUES ( 'Table'[Receive and Send Column] )
VAR __client = SELECTEDVALUE ( 'Table'[Client_name] )
VAR __other = CALCULATETABLE ( VALUES ( 'Table'[Receive and Send Column] ), ALL ( 'Table'[Receive and Send Column] ), 'Table'[Client_name] <> __client )
VAR __isExist = CALCULATE ( COUNTROWS ( 'Table' ), INTERSECT ( __other, __current ) ) + 0
RETURN
IF ( __isExist = 0, "False", "True" )

      Thanks for the quick response, I was thinking I'll probably need to convert the measure to a column. However the combining the relevant separate column values into a single colum was a great idea because it will simplify my searches later on. 

       

      Thank you!
