Hi Javier,
Have you tried by executing script mssupgsps.sql ,which you can find under D:\usr\sap\put\bin.This script will create stored procedure sap_upg_getrelease.
After execution provide grant with following
add setuser '<sid>'
grant all on sap_upg_getrelease to <sid>_shd
Hope this will help you.
Regards,
Gaurav
