What is the most efficient way to configure a calculation to sum BasePrice?

• A. Add an Aggregation Step as SUM (BasePrice)
• B. Create a Postprocessor apex class to calculate the sum.
• C. Add A Calculation Step as SUM (BasePrice).
• D. Create a Preprocessor class to calculate the sum

Answer: (A)

Aggregation steps are built to perform calculations across multiple records as data flows through, making them the right tool for totaling a field. Configuring an Aggregation Step to SUM BasePrice sums the values from all relevant rows in one declarative operation, producing a single total without writing code. Using a Postprocessor or Preprocessor Apex class would introduce custom code and run outside the streamlined data flow, adding maintenance and overhead without providing any advantage for a straightforward total. A Calculation Step handles arithmetic within a single record or isolated expressions, not cross-record aggregation, so it wouldn’t reliably produce the overall sum of BasePrice. Therefore, the most efficient approach is the Aggregation Step configured to SUM BasePrice.
