There are several ways to add variables to a mapping, as shown below.
Using a menu or toolbar command
|1.||On the Insert menu, click Variable. (Alternatively, click the Variable toolbar button).|
|2.||Select the type of variable you want to insert (simple or complex type).|
If you select "Complex type", there are a few additional steps:
|3.||Click Choose to select the source which should provide the structure of the variable (for example, an XML Schema ).|
|4.||When prompted, specify a root item of the structure. In case of XML Schemas, the root item can be any element defined globally. In case of databases, the root item can be any table.|
Using a context menu
|•||Right-click the output connector of a component (in this example, "Article") and select Create Variable from Source node.|
This creates a complex variable using the same source schema and automatically connects all items with a Copy-All connection.
|•||Right-click the input connector of a target component and select Create Variable for Target Node. This creates a complex variable using the same schema as the target, and automatically connects all items with a Copy-All connection.|
|•||Right-click the output connector of a filter component (on-true/on-false) and select Create Variable from Source Node. This creates a complex component using the source schema, and automatically uses the item linked to the filter input as the root element of the intermediate component.|
