Inconsistent measure results

Problem solved!

The main cause was that sets of effects for level 3 were not disjoint in some cases (Effect name Price was defined for more Parents). So when I used SELECTEDVALUE(T_Set_SimpleEbitda_effect[Parent]) to compare with single selected Code in hierarchy, it returned blank().

When I used VALUES instead of SELECTEDVALUE roblem was solved! 

DF Simple Ebitda breakout = 

var selStructure = [Selected Hierarchy Code]

var result = 
    CALCULATE(
        if(selStructure in VALUES(T_Set_SimpleEbitda_effect[Parent])
            , 1
            , 0)
    )
return result

 lbendlin could not see this, the data sample was too small.

Thanks for hints!
