### How to Create a New Variable

- Right click on the
**Variables**folder in the**Available Objects**window and select**New**. This opens up the**Variable Editor.** **Name**: Name the variable something descriptive**Type**: This will populate automatically after the formula is entered**Description**: This is optional; allows you to describe the variable's function**Qualification**: Dimension, Measure, or Detail (variables will automatically change to measure if there is an aggregate function)**Formula**: Type the formula for the variable into the formula pane**Validate Formula**: Tells you if the formula is defined correctly or if there are errors**Cancel**: erases any changes made within the last edit

You can use created variables in a formula or within the report in exactly the same way as you use other report objects. They will appear in the Variables folder within the Available Objects window.

- To edit a variable, double click it, or right click and choose
**Edit**. - To delete a variable, right click on the variable and select
**Delete**. This will permanently delete the variable. - To create a copy of a variable, right click on the variable and select
**Duplicate**. The copy can be edited and adjusted as needed.*This is useful when similar variables need to be created many times (very helpful for flattening data).*

Any formula created can be turned into a variable if the formula needs to be used in other formulas/variables.

## Notes

Square brackets [ ] should surround data elements. Always place a semicolon (;) between dimensions where referencing multiple data points.

Rounded Parentheses ( ) should surround and group the functions/operators to be performed; everything within the parentheses of a function or operator is related to that action

- Issues with too many or too few parentheses are common—be sure to count your parentheses to be sure you are aren’t missing any!
- If your variable doesn’t behave the way you expect, misplaced parentheses are a common culprit. Be sure you have grouped your actions they way you intended.

Formulas are performed following mathematical logic--actions are performed from the inside to the outside. Be sure to remember this as you consider the order of your formulas.

Specific considerations/actions are performed first (and will be towards the middle of a formula) and over-arching actions are performed last (and will be towards the outside of the formula).
