What is the function of the SET variable in Qlik Sense?

The SET variable in Qlik Sense is used to assign a value to a variable during the script execution phase. It allows you to define a variable that can be reused throughout your script. When you use the SET statement, it evaluates the expression that follows the equals sign and assigns that evaluated result to the variable. This is particularly useful for creating constants or storing dynamic values that may be used multiple times in your script, improving the readability and maintainability of your code.

Additionally, defining variables with the SET statement helps to maintain a clear context for your data manipulation and analyses, allowing for streamlined expressions and calculations throughout the application. The ability to store values for later retrieval is crucial in the context of data modeling and reporting in Qlik Sense, making the use of the SET variable a fundamental concept in effective data architecture within the platform.
