A variable in Qlik Sense is a container storing a static value or a calculation, for example a numeric or alphanumeric value. When you use the variable in the app, any change made to the variable is applied everywhere the variable is used. Variables are defined using the variables overview, or in the script using the data load editor, where the variable acquires its value from a Let, Set or other control statements in the data load script.
You open the Variables overview by clicking Ò in the edit bar when editing a sheet.
The following actions are available in the variables overview:
- Create a new variable.
Edit the selected variable.
- Delete the selected variable.
