In SQL tables, I could not find the name of the logged user who makes an Account Transaction.
The Ticket table do tell which user made the sale.
How can I know which user made a transaction other than a Ticket sale?
It seems that user names are only stored together with a ticket. So there is no way to know anything else a user does other than sales/tickets (purchase inventory, account transfers, etc, login time, etc).
It does not log management activity. The only stuff that is logged would be ticket related. You could create your own log system using tasks.
