ST - tt:clear , Initialization

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:

A node node specified in accordance with the addressing rules .

A variable or a

parameter variable .

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:
tt:transform
xmlns:tt="http://www.sap.com/transformation-templates"
tt:root name="ROOT"/
<(><<)>tt:template>
<(><<)>tt:ref name="ROOT">
<(><<)>X>
tt:value/
<(><<)>/X>
tt:clear/
<(><<)>/tt:ref>
<(><<)>/tt:template>
/tt:transform
During deserialization, the initial value is assigned to the ABAP data object bound to the data root ROOT .
