Accumulation Frequency
The accumulation frequency determines how often you want to calculate the value of the aggregate field. By default, most aggregates accumulate once per record. However, the following exceptions accumulate once per group:
- The field being aggregated is another aggregate field or is a calculated field that depends on the value of another aggregate field.
- Counts of group fields.
Table 5–3 describes the accumulation choices.
