Hi Experts
I am using the following dax formula to find the value in column b based on the filter selection in column A. When i have mulitple values in column B it returns bank, i want to return the first value
so
column A (Selected)
07898
Column B
Apple
Apple
so just return Apple as opposed to blank. Not sure how to use earlier in this if that applies.
Cup_h_prmry = if(HASONEVALUE(njrew_h_prmry_outcm[CUPCATNO]),VALUES(njrew_h_prmry_outcm[CUPDETAILS]),"")
Solved! Go to Solution.
Use FIRSTNONBLANK instead of VALUES.
Cup_h_prmry = if(HASONEVALUE(njrew_h_prmry_outcm[CUPCATNO]),FIRSTNONBLANK(njrew_h_prmry_outcm[CUPDETAILS]),"")
VALUES returns a column of values, which can't be displayed as a single data point. Using FIRSTNONBLANK gets the first value, depending on the current order of the data.
If you're expecting all of the CUPDETAILS values to be the same within the same CUPCATNO, I would use SELECTEDVALUE instead. This way it doesn't just pick a value randomly based on whatever ordering currently happens to be in place.
Cup_h_prmry = SELECTEDVALUE(njrew_h_prmry_outcm[CUPDETAILS], BLANK())
You can also use MAX, MIN, or any other aggregation function to determine which value to pick out of the list.
In your formula, which is A and which is B?
Apologies..
Column A =
njrew_h_prmry_outcm[CUPDETAILS]
Use FIRSTNONBLANK instead of VALUES.
Cup_h_prmry = if(HASONEVALUE(njrew_h_prmry_outcm[CUPCATNO]),FIRSTNONBLANK(njrew_h_prmry_outcm[CUPDETAILS]),"")
VALUES returns a column of values, which can't be displayed as a single data point. Using FIRSTNONBLANK gets the first value, depending on the current order of the data.

Hi
i am getting an error on the firstnonblank formula??
Cup_h_prmry = if(HASONEVALUE(njrew_h_prmry_outcm[CUPCATNO]),FIRSTNONBLANK(njrew_h_prmry_outcm[CUPDETAILS]),"")
Ah, my apologies. This is what I get for just writing in the forum and not testing it in PBI. I forgot an argument for FIRSTNONBLANK.
FIRSTNONBLANK(njrew_h_prmry_outcm[CUPDETAILS], 1)
I'm using 1 here as an always true option so that the function returns the first value it gets no matter what. You could replace it with some expression that evaluates to a value when good and a blank when bad to be even more selective about which first value you choose.
To return the first value, you can use
TOPN( 1, VALUES(njrew_h_prmry_outcm[CUPDETAILS]), 1234)
Note the last argument (1234) is where you would normally put your ordering expression. Here, I just chose an arbitrary constant value.
