    Hi, using a calculated column And DimA is 10

     

    When DimA-10 =
LOOKUPVALUE (
    Table1[Dim B],
    Table1[Ticket], Tickets[Ticket];
    Table1[Dim A], 10
)

    Using a measure:

     

    Measure-When DimA-10 =
IF (
    HASONEVALUE ( Table1[Ticket] ),
    LOOKUPVALUE (
        Table1[Dim B],
        Table1[Ticket], VALUES ( Tickets[Ticket] ),
        Table1[Dim A], 10
    )
)

    let me know if works.

    Tulio_DL,

    Create the calculated column in TABLE A.

    When DimA-10 = 
LOOKUPVALUE (
    'TABLE B'[DIM b],
    'TABLE B'[Ticket], 'TABLE A'[Ticket],
    'TABLE B'[DIM a], 10
)





    Also you can change the second formula of Vvelarde to the following:

    Measure-When DimA-10 = 
IF (
    HASONEVALUE ( 'TABLE B'[Ticket] ),
    LOOKUPVALUE (
        'TABLE B'[DIM b],
        'TABLE B'[Ticket], VALUES ( 'TABLE A'[Ticket] ),
        'TABLE B'[DIM a], 10
    )
)

I can no wrap my head around the way you are using dimension and fact tables.  I feel like you have them swapped.

Dimension tables should have unique id's...

    Hello Anonymous

     

    It really looks like....... actually it is very confusing! BUT.... that's the only way a *** system gives me the information I need

      Well, given you DO have a table of unique values, I would go ahead and create the relationship between ticket id's.  The 1 to many direction will be a bit opposite of what people think, but so be it.

       

      Now, in your table of unique values, apparently you want a new calculated column... that looks up into the non-unique table, and does *what* exactly?

        Yes Anonymous! I have already established this relationship, and yes it's totally in the opposite way...

         

        I would like to bring the information at 'DIMENSION table'[DIM b] into my 'FACT table'

         

        considering that 'DIMENSION table'[DIM a] = 10     for example
