Created By attribute

Hi Community. Within the standard PLM attributes there is the 'Creation Date' and 'Modification Date', but when trying to find the 'Created By' attribute, I couldn't find it in the standard PLM attributes. Am I missing something? There is the 'Last Modified By' attribute, which is great to retrieve information on who has released objects.

I would expect a PLM system to log the information, and it probably does, but how do I retrieve or filter on this attribute?

Thanks in advance.
