Report Painter

Hi All,

My client needs to generate reports that are not standard in SAP. Examples of these reports are aging for customer accounts (less than 30 days, 30 days to one year, 1 year to 5 years and more than 5 yrs), rollforward analysis reports for customer balances, etc. Can these be handled through report painter? Can anyone send me a guide for report painter? Please advice. Thank you!
