Thank you so much,
I don't know why nor how but it works perfectly.
Can I ask you something more about my Month dim :
I Add this in the script to convert it as month dimension to get the value in right order and not alphatebical order
month(date#('$(MoisNb)','MMM')) as "Mois",
but it does'nt load the sheet "mai"
I think it's because of this in my script :
I Use this to take only sheet name different from S1 to SXX and sheet name different from T1 ou T4
but it cause a missing load with mai in my month calendar.
Do you see another way to excluse weeks en quarter sheets ?
Once again thank you very much for rapid answer
