Use Variables

Variables are Mapping Services objects that store and pass values. Variables are self-contained and reusable units that you create, access, and work with in a WorkFolder in a DML Mapping Project.

When you create a Variable, you can use a DML expression to assign an initial value to the Variable. During the execution of a Mapping Flow, this initial value cannot be reinitialized. However, you can define expressions that assign (set) a new value to the Variable.

You can use a Variable to pass one or more values between the objects that the integration application uses to process a given Business Document ,shown in the following graphic:

From the moment the integration application parses an input Business Document to the moment the integration application generates the appropriate output Business Documents, it can use one Variable to work with the values in those Business Documents.

You can use a Variable:

In the object... In...

Input Business Document

Validation Rules that verify that the required content is present in the input Business Document.
