New Column based on values from a different table

[Anonymous]

Hi all, 

I have a table with customer ID and postcode they live in (table A) and another table with postcodes and regions (Table B). I would like to create a column in table A with the Region related to the postcode. 

i have tried the merge function but it looks like the final table is not right! Also playing with a lookupvalue function, however I am getting the "a table if multiple values was supplied where a single value was expected" error

Any help would be greatly appreciated

Hi @Anonymous ,

If the postcode column has unique vaule in the table B, the lookupvalue should work fine as following calculate column

Region = LOOKUPVALUE('Table B'[regions],'Table B'[postcode],[postcode])

If one postcode has multi region, you can give me the expected result based on my sample data.

BTW, pbix as attached.

Hi,

You will need to join the two tables using postcode field and use below dax to create a calculated column in Table A to get the region field from Table B.

Region = RELATED( Table B[Region] )

Thanks.

Tried it, but I am getting an error saying that the region field is not recognised as there is no relationship between the two tables, even thoug hI created the relationship already. 

Is there anything iam missing?
