Using the Use Accumulator Standard Rule

The Use Accumulator standard rule gives you access to a set of numeric variables that you can manipulate using numeric operations, and then transfer to and from fields. This rule enables you to add, change, or delete calculations for the field, including hash totals (used to accumulate numeric field values such as quantity and price). This rule also enables you to map the accumulated total into a control total field, and use accumulators. Accumulators count the occurrences of a specific field or generate increasing, sequential record, or line item numbers.
