This option sets the default age periods for the Age command (0, 31, 61, 91, 121, 151, 181 and 10,000 days). If you use a specific set of age periods frequently, you can enter the set in the Periods text box. Analyzer uses the setting in the Periods text box as the default Age periods (buckets) for the Age command. This saves you from having to change the default age periods every time you use the Age command. You can still override the periods in the Age dialog, when you need to.
Enter the periods in days, separated by commas without spaces. You can set as many age periods as you wish.
