VAR doesn't work
Dear all,
I tried to use VAR in PowerBI but without success.
Here below my measure:
MaxTest =
VAR LVL1 =
COUNTAX ( LIMLOGN; FILTER ( ALL ( LIMLOGN[LvlCode] ); LIMLOGN[LvlCode] = 1 ) )
VAR LVL2 =
COUNTAX ( LIMLOGN; FILTER ( ALL ( LIMLOGN[LvlCode] ); LIMLOGN[LvlCode] = 2 ) )
VAR LVL3 =
COUNTAX ( LIMLOGN; FILTER ( ALL ( LIMLOGN[LvlCode] ); LIMLOGN[LvlCode] = 3 ) )
VAR LVLTOT =
COUNTAX ( LIMLOGN; ALL ( LIMLOGN[LvlCode] ) )
RETURN
IF (
IF ( LVL1 >= LVL2; IF ( LVL1 >= LVL3; LVL1; IF ( LVL2 >= LVL3; LVL2; LVL3 ) ) )
< LVLTOT;
"Y";
"N"
)
When I try to put this measure into a Pivot table I will obtain the following error:
Mdx Script (Model) (9, 24) Calculation error in the measure 'LIM LOGN' [MAXTEST]: You specified a table of values as expected while a single value.
I have built 4 Variables and I'd like to find the maximum between LVL1,LVL2,LVL3
Then I need to compare the Max with LVLTOT and return "Yes" or "Not".
Could you help me to understand where is my error?
Thank you
Lara
The expressions will have to be written as follows
VAR LVL1 =
COUNTAX ( FILTER ( LIMLOGN, LIMLOGN[LvlCode] = 1 ) ,LIMLOGN[LvlCode] )
VAR LVL2 =
COUNTAX ( FILTER ( LIMLOGN,LIMLOGN[LvlCode] = 2 ), LIMLOGN[LvlCode] )
VAR LVL3 =
COUNTAX ( FILTER ( LIMLOGN, LIMLOGN[LvlCode] = 3 ) ,LIMLOGN[LvlCode] )
VAR LVLTOT =
COUNTAX ( ALL ( LIMLOGN ) ,LIMLOGN[LvlCode] )
RETURN
IF (
IF ( LVL1 >= LVL2; IF ( LVL1 >= LVL3; LVL1; IF ( LVL2 >= LVL3; LVL2; LVL3 ) ) )
< LVLTOT;
"Y";
"N"
)It should work.
If this works please accept it as a solution and also give KUDOS

Your syntax is wrong in all of those COUNTAX formulas. The syntax for COUNTAX is =COUNTAX(<table>, <expression>) but you seem to have written it as =COUNTAX(<table>, <table>). The FILTER statement should be your first argument and the second should be an expression to be evaluated on each row. So VAR LVL1 = COUNTAX( FILTER( ALL (LIMLOGN), LIMLOGN[LvlCode] = 1), <insert whatever expression you're trying to evaluate here>)
But if I understand the results you're trying to get, I don't think you should even be using COUNTAX in the first place. If you just want to count the rows in a filtered table you should use COUNTROWS instead of COUNTAX. COUNTAX should be used if you want to evaluate some expression on each row of a table and count the results of that expression. So if you just want a count of all rows where LIMLOGN = 1, it should be
VAR LVL1 = COUNTROWS(FILTER( ALL (LIMLOGN), LIMLOGN[LvlCode] = 1))
The error is in the variable LVLTOT:
VAR LVLTOT =
COUNTAX ( LIMLOGN; ALL ( LIMLOGN[LvlCode] ) )But I don't understand the reason... Any suggestion?
Thank you
LaraHi larabraghetti. I don't see anything explicitly defined for when LVL1 < LVL2, as in:
IF ( LVL1 >= LVL2; IF ( LVL1 >= LVL3; LVL1; IF ( LVL2 >= LVL3; LVL2; LVL3 ) ); LVL2 )
I'm also not sure how this would ever evaluate to anything but "N". Isn't a part of the whole always less than the whole? If you get the count of a column where the code is only 1, and then a count of the column where the code doesn't matter at all, wouldn't the second calculation always be greater than the first? Sorry if I'm missing something.
The expressions will have to be written as follows
VAR LVL1 =
COUNTAX ( FILTER ( LIMLOGN, LIMLOGN[LvlCode] = 1 ) ,LIMLOGN[LvlCode] )
VAR LVL2 =
COUNTAX ( FILTER ( LIMLOGN,LIMLOGN[LvlCode] = 2 ), LIMLOGN[LvlCode] )
VAR LVL3 =
COUNTAX ( FILTER ( LIMLOGN, LIMLOGN[LvlCode] = 3 ) ,LIMLOGN[LvlCode] )
VAR LVLTOT =
COUNTAX ( ALL ( LIMLOGN ) ,LIMLOGN[LvlCode] )
RETURN
IF (
IF ( LVL1 >= LVL2; IF ( LVL1 >= LVL3; LVL1; IF ( LVL2 >= LVL3; LVL2; LVL3 ) ) )
< LVLTOT;
"Y";
"N"
)It should work.
