About Semantic Model (Repository) Variables
A semantic model (repository) variable is a variable that has a single value at any point in time.
Semantic model (repository) variables can be static or dynamic. A static semantic model (repository) variable has a value that persists and doesn’t change until the administrator changes it. A dynamic semantic model (repository) variable has a value that is refreshed by data returned from queries.
Modelers define dynamic and static semantic model (repository) variables in Data Modeler. The Update Value option determines whether a variable is dynamic or static. For dynamic variables, Update Value = On a Schedule. For static variables, Update Value = Never.
