In a calculation procedure, what is required for the output of a calculation step to be usable in an aggregation step?

• A. It must be included in constants.
• B. It must be a matrix lookup step.
• C. It must be a calculation step.
• D. It must be included in the calculation output.

Answer: (D)

The important idea is that only values that are published as part of the calculation output can be used by later steps like aggregation. In a calculation procedure, you perform various steps, but unless the result of a step is explicitly exposed in the calculation output, downstream steps won’t see it. To feed a result into an aggregation, you must assign that result to a named output within the calculation output, making it accessible to the aggregation step. Constants aren’t dynamic results from a step, and a matrix lookup is just another step type; neither is automatically exposed to aggregation unless you publish its value in the calculation output. The key requirement is publishing the result to the calculation output so the aggregation step can consume it.
