Hi SK SK,
According to my understanding goes the creation date is the date when COGI was created for the first time. This time both the dates will be same.
Now suppose, after two days someone again tries to clear the COGI and gets error saying 'deficit of stock', this time the error date will be two days later then the created on date.
Hope it is clear to you.
Thank you.
