Thank you all for Support are able to obtain the desired result.
I used to like you suggested the function week and I got the following result:
I simply wrote the script:
Date#(Lower(Mid(@4,2,11)),'DD/MMM/YYYY') as DATA,
Week(Date#(Lower(Mid(@4,2,11)),'DD/MMM/YYYY')) as Settimane,
Thank you very much
