How to name parameter form for SysOperation batch job task in d365?

I have created a batch job using the SysOperation framework, I want to set title of the form which shows the parameters of the job. How can I do that?

The title is already shown is the name of the service class and the entry point method. This is the dialog

you must add this method :

protected ClassDescription defaultCaption()
{
    ClassDescription ret = 'your caption';
    return ret; 
}
