Just want to have some dummy data for test purposes and I'm new to SN scripts. 
Created this but yet to test:

var gr = new GlideRecord('sn_hr_core_case');
gr.initialize();
gr.short_description = current.short_description;
gr.assignment_group = current.assignment_group;
gr.work_notes = current.work_notes.getJournalEntry(-1);
gr.insert();

instead of 

gr.work_notes = current.work_notes.getJournalEntry(-1);

You need to gliderecord the sys_journal table and copy the records.
