Which version of a Constant will an expression reference?

When an expression references a Constant in Appian, it points to the most recent version of that Constant. This is because Appian maintains a history of constants and allows users to update them as needed. However, when working with expressions, it's essential to reference the current state of the Constant to ensure that the most up-to-date value is used in calculations or business logic.

The most recent version is significant in maintaining data integrity and ensuring that applications behave as expected. When a Constant is updated, any expression that references it will inherently use this latest version. This approach also prevents confusion that could arise from referencing older versions or trying to manage the use of multiple versions simultaneously.

This understanding of versioning is crucial for developers who need to ensure that their applications utilize the current configuration and logic defined by the most recent Constant.
