Bulk Update Fix Scripts - Work notes should be updated by system user? URGENT

[saint]

Hi Experts,

I'm writing a bulk closure script for incident and sc tasks, i want to add comments to the tasks as a system user. currently it takes logged in users name. I tried with setJournalField 

gr.setJournalEntry('work_notes','TEST','userid');

and with

setValue('work_notes','TEST','userid');

Need urgent assistance.

Hi @saint 

autoSysFields(false): It is a GlideRecord method used in scripts to prevent system metadata fields—such as sys_updated_on, sys_updated_by, and sys_mod_count—from being updated when a record is modified. It is commonly used for data fixes or silent updates to avoid altering record history

Also few  tips when running fix scripts to update records in bulk :

Test in Sub-Prod: Run this script in a lower environment (Dev/QA) first.

setWorkflow(false): This prevents triggering unnecessary notifications, SLA updates, or related Business Rules.

Use setLimit(100): Initially, only update a small batch like 50/100 to ensure the code behaves as expected.
