How does the LET variable operate in Qlik Sense?

The LET variable in Qlik Sense operates by evaluating the expression that follows the equal sign. This means that any calculations, string manipulations, or other expressions contained in that text are evaluated, and the result is assigned to the variable. For example, if the expression includes mathematical operations or functions, those will be computed, and the final result will be stored within the variable for further use in the data model or visualizations.

This mechanism allows for dynamic values to be calculated and assigned at runtime, making it a powerful tool for data manipulation and analysis within Qlik Sense. The ability to perform evaluations on expressions ensures that users can create variables that adapt based on the underlying data and are not merely static strings or fixed values.

While other options suggest different functionalities of variables, they do not accurately describe the operational capacity of the LET statement in Qlik Sense. The versatility of LET enhances data expression capabilities, providing users with dynamic and calculated values that can be leveraged throughout their applications.
