Hello Gabriel,
You can track the document from the (process) reports and once you open the particular instance from the process you can find the information you need..
Once you open the Parameters tab of the instance, you'll find the Internal Parameters
and P_initiator where the user's name is stated
Also, in the next section, P_result gives you the date (created) variable
I hope this has helped, if you need further explanations, please let me know.
Thanks.
Kind Regards,
Zdravko Lazarevski
