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
The variable is created. Specify the Variable context attribute of the Process automation attribute type group. If you do not specify this attribute Process instance is used automatically as the default value.
You have placed the variable.
You have modeled a variable. You can use it in the data flows of all objects.
You can use multiple variables in a data flow diagram for a function and connect them with fields of the function. You can also use multiple variables in a data flow diagram for a function with the Function symbol. You can use a variable in a data flow multiple times. Since a data flow is modeled graphically, you cannot influence a specific value of a variable.
