Ah I see. So it will audit all the custom fields. Do many see a performance hit?
If you audit the entity for custom fields of EVNT you should get all the custom fields that you can see on the work order screen.
Now I have another issue...only two of our custom fields are associated to an Entity.
Yes, what you do is go to the Audit Setup screen. Then click on the Comments and Custom Fields tab and choose the entity the custom field is associated to during the set up of custom field. Once on that row then check the appropriate box. Hope this helps
