Hi all,
I am trying to create a relationship between two tables.
Table 1 ('CLTV') contains all transactions, including the User_ID for the customer making each transaction.
Table 2 is a calculated table created using DISTINCT(CLTV[User_ID]), so by definition each item in that table must be distinct.
Firstly, when I try creating a relationship in the Relationships page by dragging and dropping, Power BI crashes (the "SQLDUMPER.EXE" issue that has been raised elsewhere).
However, when I try creating a relationship between the two tables using the "Manage Relationships" button on the ribbon as advised in the thread above (with User_ID as the relationship column in both tables), it gives me the following error:
This makes no sense to me - as I mentioned above, I used the DISTINCT function to create the column in Table 2 that I am using for the relationship, so there is no way that the column in Table 2 does not have unique values. I also tried using VALUES, which didn't work either.
I have created relationships in the past using exactly the same logic and have never had a problem - has anybody else come across this error?
Thanks
Solved! Go to Solution.
You may use the formula below.
Table = FILTER ( DISTINCT ( CLTV[User_ID] ), NOT ( ISBLANK ( CLTV[User_ID] ) ) )
You may use the formula below.
Table = FILTER ( DISTINCT ( CLTV[User_ID] ), NOT ( ISBLANK ( CLTV[User_ID] ) ) )
Thanks for the replies - both are correct; accepted @v-chuncz-msft as it's a more direct solution.
Hey,
look if you have (Null) value and maybe an empty value '' in your table. As far I can remember both are treated equal for an relationship. So you have to filter them out
