Environment : Prod and Test
I have set Data update log to Y for SKU and Package module, to see who edit these 2 modules.
Then I have try edit by myself to see if any log showing, but there is no any log.
Could you please check if I did something wrong or the system bug.
Need to set this system config DATA_UPDATE_LOG = Y. If you need more information, you can check it int the TEST environment.
