I have SalesFact and DimCustomer table.
SalesFact have CustomerId, TransactionId, SalesAmt. There are thousands of rows for same CustomerID. (currently for testing I'm using only 1 CustomerId)
DimCustomer have CustomerId, CustomerName.
Power BI cannot make relationship between because is says that one of one of the tables must ba unique value. Should I create new calculated table or what should be done?
Solved! Go to Solution.
Hi @Anonymous,
Create a new table using the following DAX expression.
CustomerId = FILTER( DISTINCT( UNION( DISTINCT(SalesFact[CustomerId]), DISTINCT(DimCustomer[CustomerId]) ) ), NOT(ISBLANK([CustomerId])) )
Then create relationship among CustomerId , SalesFact and DimCustomer tables as follows.
Thanks,

CustomerID must be unique in the customer table and also no blanks.
