DAX Column - use another value if field is blank

[PhoenixBird66]

I am trying to create a DAX column or measure (not sure which would be best) and I'm not sure of the best way of doing this.

If the value in the Standard Service Code column is blank, I want the DAX mesaure to returns the first Standard Service Code from another row with the same document number.

So in the second and third rows in the picture below, the new measure/column would give you the standard service code of the first row (as all three rows have the same Document No_). Hope that makes sense? Any thoughts on the best way to do this?

Couldn't you also do a fill down in the query?

This is how I acheived it in Excel (see last column Test), using this formula:

=IF(A2=A1,E1,C2)

I just don't know how to translate that to DAX 😞

Hi,

According to your description, i create a simple table to test:

Please try to create this calculated column:

Column = IF('Table'[Standard Service Code]=BLANK(),CALCULATE(MAX('Table'[Standard Service Code]),ALLEXCEPT('Table','Table'[Document No])),'Table'[Standard Service Code])

And the result shows:

Hope this helps.

Try

std service code = minx(filter(table,table[document_no]=earlier(table[document_no]) &&  not(isblank(table[standrad service code]))),table[standrad service code])
OR
std service code = minx(filter(table,table[document_no]=earlier(table[document_no]) &&  not(isblank(earlier(table[standrad service code])))),table[standrad service code])

Thanks for the suggestion, but sadly, neither of these work.

Here are my 2 attempts and a screen shot of the results.

Column = MINX(FILTER('US_Invoice Line', 'US_Invoice Line'[Document No_]=EARLIER('US_Invoice Line'[Document No_]) && NOT(ISBLANK(EARLIER('US_Invoice Line'[Standard Service Code])))), 'US_Invoice Line'[Standard Service Code])

And

Column 2 = MINX(FILTER('US_Invoice Line','US_Invoice Line'[Document No_]=EARLIER('US_Invoice Line'[Document No_]) && NOT(ISBLANK('US_Invoice Line'[Standard Service Code]))), 'US_Invoice Line'[Standard Service Code])

This is what they returned:
