How to update comments without mentioning the user name. It should be as system.

[Sunny4]

I have a requirement :

ticket is automatically closed via workflow activity with comments and closed notes. Now the comments should not updated by the current user. It should be displayed as System updated the comments.

If you add a timer it will do the Workflow steps after it as system (as it will run asynchronous):

Other option is add a script action and script it like they did here in a business rule (so use it in script block in workflow and make changes accordingly):

you can use

current.comments.setJournalEntry(your comments, 'system');
