Variable strange behavior in a measure, report only if substract a number

[Pier2]

Hello,

I have a variable in a measure who returns a value only if I put a minus number at its end but nothing otherwise.

I use integer to identify years.

I want to report a trend, minus the year cicled in red.

The formula is the following to be sure to see the entire graphic:

m_CoutCapitauxPropres = 

VAR varPrem = 
CALCULATE(
    MIN(tblEntrepriseDonnees[intAnnee]), USERELATIONSHIP(tblEntreprise[KEntreprise],
    tblEntrepriseDonnees[FKEntreprise]) 
)-1
     
RETURN



CALCULATE(
SUM(tblEntrepriseDonnees[sglCoutCapitauxPropres]),
FILTER(
CalendrierAnnuel,
CalendrierAnnuel[Année fiscale]  > varPrem
), USERELATIONSHIP(tblEntreprise[KEntreprise],
    tblEntrepriseDonnees[FKEntreprise])
)

 

Should I simply replace -1 for nothing, zéro or +1, everything vanish.

m_CoutCapitauxPropres = 

VAR varPrem = 
CALCULATE(
    MIN(tblEntrepriseDonnees[intAnnee]), USERELATIONSHIP(tblEntreprise[KEntreprise],
    tblEntrepriseDonnees[FKEntreprise]) 
) // Nothing is substracted or added to the evaluation
     

What's the logic behind that behavior? How to solve it? The best solution, for me would be to replace -1 for nothing.

Hi @Pier2 ,

Could you please take this DAX out and create a measure to see whether it returns a null value?

CALCULATE(
    MIN(tblEntrepriseDonnees[intAnnee]), USERELATIONSHIP(tblEntreprise[KEntreprise],
    tblEntrepriseDonnees[FKEntreprise]) 
)

Hello @Anonymous ,

Thanks for your help.

That formula returns effectively a value, which is the right value in its context, the year 2015. That's something I already verified in different ways.

In the RETURN part of my formula, should I change the variable varPrem for an integer (2015, for exemple) it works perfectly. It's like the variable varPrem doen't convey the value to the RETURN.

On the data side, the table looks like this. The year 2015 (the first of the graph) has no ratio calculated and when its the case, I try to get rid of it because that's meaningless. And I starting to believe it is the source of the problem but I don't know why.

intAnnee (year using integer)	sglCoutCapitauxPropres
2015
2016	0,04
2017	0,05
2018	0,00
2019	0,12
