Variables
A variable is a data value that can be a static or a dynamic value based on your requirement.
Here we have two types of Variables in Report V2 based on the scope of their usage:
Local Variables: These variables can be used only within the scope of the Report in which they are created.
Global Variables: These variables can be used in any report.
How to create/add Local variables in Report V2:
First, you need to go to the Custom Tab alongside the Column tab.
Now go to the Variable Section and click on it.
A dropdown will open up.
You now need to select the Variable type Local and click on Add Variable button.
Now Add Variable window will open. It has the following components:
Variable Name: This allows you to name the Variable you want to add.
Label: This allows you to add a Label to your Variable.
Data Type: This allows you to choose the Data type of the Variable's value. It can be Text, Date, and Numeric.
Input Method: This allows you to choose the input method for Variable entries such as Type In, Pickup List, or both combined.
Default Value: Here you need to specify the default values for the Variable as per your need.
For Type In variables- You need to specify a single Default value.
For Pickup List variables- You need to give multiple comma-separated values as default values. Then you can choose the desired Variable value from the Pickup list.
Now click on Add button and your Local variable will be added.
Note**: Global variables can only be created in Admin >> Settings>> Global Variable.
Where to Use Variable in Report V2:
You can use the Variable in the following features:
Custom Columns: You can use variables to create a new Custom Column.
For eg: Let's say you have Employees data and you want to create a new column "Employee Status" having two values "New" and "Old" calculated based on the fact whether the Joining date for an employee is after a certain(2023-01-01)date or not. To achieve this you can use a Variable with Date data type with the defined default date value as '2023-01-01' which you want to use for the comparison between New and Old employee. You then need to use this defined Variable in the "Case When" SQL query to create the Custom Column "Employee Status" and then you can change this Variable Date value according to your need to separate employees into New or Old.
Custom Metrics: You can use variables to create new Custome Metrics.
For Eg: If you have Banking Loan data and you want to create a new Metric "Total Payout" calculating the total loan amount to be paid over a tenure based on different sets of Interest rates 10%, 15%, 20%, etc. Here you can use a Variable with a Numeric data type named "Interest Rate" with some default value like 10 and use this for the Custom Metric creation. So now you can later change the variable value to some different interest rate based on which new "Total Payout" will be calculated.
Custom Filters: You can use variables to create new Custom Filters as well.
Note**:
To identify the variable in an expression, use {{variableName}} and enclose it within curly brackets.
To identify the global variable in an expression, use {{Globals.variableName}} and enclose it within curly brackets.
Once the Variable has been created and used in some Custom calculations then you can directly change it in the Reports' View Mode itself.
When you will open any Report with Variable enabled Custom calculations then in the View mode itself you will have Variable Panel on the left-hand side from where you can modify the Variable and run the Report to see the changes.
