The Set Node is used to set a value in the schema or in a public variable.
The value which is set into the schema location or public variable can come from the schema, a public variable or a literal value. As an example, shown below, the value of KWID (in the Profile section of the Schema) is set to a literal "firstName".
The Set Node returns true if it was successful - it does not return the value of the value which was set. The Set Node is a shortcut for copying values between data locations.
