Solved

Simple multiply between to fields without direct releation

 

Hello,

 

I need your help to resolve a simple problem (I'm beginner) and escially to identify the best solution !

 

I want to calculate Tonne CO2  = Population[Nombre] * TonneCO2ParHab[Tonnes de CO2 Par Habitant].

 

You can see relationships here

 

The link between data is the Year (Année) AND the Country code (Code Pays).

If I want to add relationships for Année it's not possible (* *).

 

Thanks in advance and Regards.

 

Seby

    It don't work with these cardinality values. But I have the solution : 

    Tonnes CO2 = TonneCO2ParHab[Tonnes de CO2 Par Habitant] * CALCULATE(FIRSTNONBLANK(Population[Nombre];1);FILTER(Population;Population[Année] = TonneCO2ParHab[Année] && Population[Code Pays] = TonneCO2ParHab[Code Pays]))
     
    Thank you az38
