I think you can check in your expression whether the dimension is Min or Max and otherwise results in Null?

If(Dim=Min(Dim) or Dim=Max(Dim), expression, null())

it only shows the value of the selected month

the expression is:

=Sum({$ <Année= {$(=Only(Année))},Mois={"<=$(vThisMonth)"}>}[1.4])

/Sum({$ <Année=  {$(=Only(Année))},Mois={"<=$(vThisMonth)"}>}[1.3])

The dimension is the Month

Thank you for your help
