Use ALLNOBLANKROW with UNION

[Anonymous]

I have made a table joining two columns using UNION taking only DISTINCT values.

That works fine, but I also need the blanks to be removed.

I have tried using ALLNOBLANKROW, but can't seem to make it work.

Is there any way to get rid of the blanks using DAX?

Casenumbertable = 
DISTINCT (
    UNION (
        SELECTCOLUMNS ( testcare; "casenumber"; testcare[CaseNumber] );
        SELECTCOLUMNS ( tvs; "casenumber"; tvs[CaseNumber] )
    )
    )

ALLNOBLANKROW serves a different purpose, it removes the optional blank row to fix invalid relationships and it has nothing to do with blank removal (I know, the name is somewhat confusing... but it would have been hard to find a better one).

That said, you can remove blanks after the UNION is finished:

Casenumbertable = 
DISTINCT (
    FILTER ( 
        UNION (
            SELECTCOLUMNS ( testcare; "casenumber"; testcare[CaseNumber] );
            SELECTCOLUMNS ( tvs; "casenumber"; tvs[CaseNumber] )
        ),
        NOT ISBLANK ( [CaseNumber] )
    )
) 

This should do the trick.

Have fun with DAX!

The Solution works for me whilw using Summarize with union 🙂

Thank you Alberto 😉

That does the trick Alberto!

A small correction is needed though, since I'm using ";" and not "," for making breaks.

I guess this is due to different local version quirks of Power BI.

Below is my European version of the code:

Casenumbertable = 
DISTINCT (
    FILTER ( 
        UNION (
            SELECTCOLUMNS ( testcare; "casenumber"; testcare[CaseNumber] );
            SELECTCOLUMNS ( tvs; "casenumber"; tvs[CaseNumber] )
        );
        NOT ISBLANK ( [CaseNumber] )
    )
)

Yeah... I find this stuff of "," and ";" so annoying that I ended up setting all of my PCs with American standard, at least I can write code the way I like, with commas as separators.

After some time, you also get used to the funny way they express dates "mm/dd/yyyy". It still does not make a lot of sense, yet you get used to it 🙂

Have fun with DAX!

Hi @Anonymous,

As a variant you can filter blank rows by report/visual filter.

Not what I'm looking for, but thanks for the effort.

The table will serve as a relation(primary key) between two tables between two other tables, so the blanks need to be gone.
