Table and relationships

You can create a measure that looks to see if the montant > budget

test measure = if(sum(montant) > sum(budget), true(), false())

you can then add this measure to your visual filters use it to filter the data. 

or you can set montant to blank() if the budget is greater

like montant = if(sum(montant) > sum(budget), sum(montant), blank())

and then filter the visual to only show rows with non blank Montant values.

Hope that helps,

Hey,

maybe you can try the RELATEDTABLE() used in a CALCULATE() like so

Bust = 
IF(CALCULATE(SUM('CHARTE'[Montant]), RELATEDTABLE('CHARTE')) >
CALCULATE(SUM('BUDGET'[Budget]), RELATEDTABLE('BUDGET')),1,0)

RELATEDTABLE() is the opposite from RELATED. RELATETABLE pulls from the many side, for this reason it is necessary to provide an aggregate function.

Hope this helps
