[a.info]

Hello,

I want to create a report in Report Studio by analyzing my AC indicator (previous month, days spent in the current month, day future of the current month and the following month).

If the user will run the report for example in '15 January', I want have in my report: month of December, days spent in the month of January, the future day month January and February.
The values ​​for future days and months are calculated from the value bygone days of the current month * rate.

Thank you for your help.
