Do you have to be a Great Plains System Administrator to make changes to Auditor?
No. Whomever has Security access to the Auditor Group Maintenance window can add create new Form and Table groups or edit existing groups. To create a SQL Table audit the user will need at least enough SQL access to create SQL Triggers.
Note: Auditor will only appear on the Great Plains menus for sa or DYNSA. Other users will need to add the Group Maintenance window to their Shortcut Bar.
