What is the most efficient way to calculate the sum of the BasePrice field in a calculation procedure?

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

Answer: (C)

In a Calculation Procedure, use a Calculation Step to perform arithmetic and aggregation directly within the flow. Using a Calculation Step with SUM(BasePrice) computes the total in the calculation itself, keeping the logic declarative, close to the data, and executed as part of the procedure. This is faster and simpler than introducing custom Apex (Preprocessor or Postprocessor) code, which adds maintenance and extra processing steps. It’s also more straightforward than an Aggregation Step for this scenario, since a simple sum of a single field in the procedure is efficiently handled by the Calculation Step without the overhead of an additional aggregation construct.
