IntelliJ IDEA generating serialVersionUID

How do generate this value in IntelliJ IDEA?

I go to Settings -> Errors -> Serialization issues -> Serializable class without ‘serialVersionUID’, but it still doesn't show me the warning. My class PKladrBuilding parent implements interface Serializable.

Part of the code:

public class PKladrBuilding extends PRQObject
public abstract class PRQObject extends PObject
public abstract class PObject implements Serializable
