Syntax
<tt:clear [ref="node"|var="variable"] />
Effect
You can use the statement tt:clear to initialize a data root, a variable, or a parameter.
You use ref or var to specify the field that you want to initialize. If no field is specified, the current node is used implicitly. The following fields are possible:
Serialization
During serialization, only variables (or parameters) are initialized. If a node is specified with ref or if the current node is specified implicitly, tt:clear has no effect during serialization.
Deserialization
During deserialization, the specified nodes or variables (or parameters) are initialized.
Example
The transformation below shows an initialization:
During deserialization, the initial value is assigned to the ABAP data object bound to the data root ROOT.
