Which statement about aggregations per row is correct?

• A. Only one aggregation per row is allowed
• B. Multiple aggregations per row are allowed
• C. Aggregations do not apply to rows
• D. Aggregations are optional

Answer: (A)

When aggregations are applied at the row level, you’re collapsing the values within that single row into one summary. Allowing more than one aggregation on the same row would create ambiguity about which values are being summarized and how their results should be combined. To keep results clear and deterministic, the rule is that only one aggregation per row is permitted. If you need additional metrics, you would create separate calculated fields or use additional rows/contexts to produce those summaries rather than stacking multiple aggregates on a single row. The other statements don’t fit because aggregations do apply at the row level, and the constraint is about limiting to one per row rather than making them optional.
