You can create a new variable.
Variables are task-independent data placeholders. A function or an event can store a value in a variable, and another function or event can extract and use this value in a later process step.
Variables should be used in governance workflows only if required. For the standard data flow between the various activities, the activities themselves should be used as input. The data should not be unnecessarily stored intermediately in variables as this may have a massive impact on the entire performance of the governance workflow.
Prerequisite
At least one variable catalog exists as a model of the IE Data model type in your database.
Procedure
Activate the Variables and constants bar.
Activate the Variables tab.
Select a variable catalog.
Click New. Specify name, type, scope, and the initial value (not for the Collection type).
Click OK.
You have created a variable. This variable is created and saved automatically in your variable catalog.
