Why this LOOKUPVALUE does not work?

Hello

Can you tell me please why this LOOKUPVALUE in a calculated column in Table1 does not work?

 

LOOKUPVALUE('Table2'[Column3],'Table2'[Column1],Table1[Column1])

Error: A table of multiple values was supplied where a single value was expected.

 

Thanks

    you need to define business rule what exactly row whould be chosen for these cases

      Hi, do you mean there are duplicates in these columns? And I need to specify which one to consider? How can I specify that?

        yes

        you have more than ine result resulted by your condition. you should define what result to choose. MAX() or MIN() or AVERAGE or FIRSTNONBLANK. there is a lot of possible solutions depending on your logic. you can create a column like

        CALCULATE(FIRSTNONBLANK('Table2'[Column3], 1), FILTER(ALL(Table2), 'Table2'[Column1] = EARLIER(Table1[Column1]) ) )

    Hi,

     

    It is because there are more than one same value in 'Table'[Column 1].

    Please check it.
