About aged summaries

Using a date or datetime field in a table, you can group records into aging periods measured in days, and produce an aged summary of the data. Although you can age on datetime values, only the date portion of the values is considered. The time portion is ignored. You cannot age on time data alone.

Aging periods are based on date intervals (that is, number of days) measured backward in time from the current system date, or from a cutoff date you specify such as a fiscal period end date. Common uses of aging include evaluating sales trends, looking at transaction volumes, and grouping invoices by the number of days outstanding.

You can specify date intervals such as 0, 90, and 120 days as starting points for aging periods, or you can accept the default settings of 0, 30, 60, 90, 120, and 10,000 days. An interval of 10,000 days, or an appropriate final interval you specify, is used to isolate records with invalid dates.

Aging in detail

Aging counts the number of records in a table and performs the following operations:

Table 1. Operations performed by aging


Location in Figure 1

Groups the records into aging periods based on cutoff date and date intervals

Days field

Subtotals the number of records in each aging period, and calculates the percentage of the total count represented by each subtotal

Count field

Percent of Count field

Provides the minimum and maximum ages of records (that is, the most recent and the oldest)

not shown

Optionally subtotals the values of one or more numeric fields for each aging period, and for the first selected field calculates the percentage of the total value represented by each subtotal

Trans Amount field

Percent of Field field

Optionally breaks down the output results based on the values in a character field such as customer ID or transaction type (requires that the character field is sorted prior to aging)

not shown

Provides totals for all fields included in the output results

Totals row

If you output the results to screen or graph, the graph displays the count subtotals for each aging period, or the numeric subtotals if you include one or more numeric fields in the aging operation.

Figure 1 provides an example of the results produced by aging an accounts receivable table (the ‘Ar’ table in ACL DATA\Sample Data Files\Sample Project.ACL) and outputting the results to screen.
