Including current year and week of the year in ESM reports

Hi everybody,

I need to schedule weekly reports in ESM and send them by email and, in the email subject, it must be specified the current week of the year when the report is being submitted.

Does anyone know how this can be accomplished? I've carried out several tests and it seems to be working only with a few variables like $Now, $Today, $CurrentWeek, ...

Thanks a lot in advance,
