Hello together,

This is an issue in V15 but think it is a general question for nearly each Odoo Version.

To reproduce the issue you can follow this steps:
Create a Time Off Request and submit this for approval

Login as approver to Time Off and refuse the request.
Login as employee and check the chatter.

How is it possible to deactivate the yellow displayed system message without modifying the python code?

Also how can other such system messages be identified in Odoo.

Thanks and greetings

Michael
