Hi,
I want to have a month and a year in a report. It's seems easy but I can't managed to get the yyyymm as title of the PDF file. It's about last month data.
For example on the first day of the new month I have scheduled a report that will show the performance of the mem en cpu of last month. When I edit the report there is no option for a SQL query:

When I schedule this report I can use a variable to get some output (not in/on the pdf) in the subject of the mail but how can I get the last month and not the month that I have start the report. In the example you ca see the month as is, but I want to see last month number 06 (june):

Please advice.
Regards,
Remi
