A company uses Expression Sets to determine product pricing.

Rank (A) – The Expression Set with the highest rank is selected by the Calculation Engine when multiple active Expression Sets exist for the same date.

This ensures that the most relevant pricing rule is applied based on the company’s prioritization strategy.

B. Date modified – The modification date does not determine priority for execution.

C. Date created – The system does not use the creation date to prioritize which Expression Set to execute.

D. Sequence – Sequence applies within an Expression Set but does not control selection between multiple active Expression Sets.
