Dynamics GP - Field Service - How to find out Which User Created/Modified an Equipment ID?

Activity Tracking does not track any of the Field Service Tables.
The only thing it will track is opening and closing of the windows.

This table has a log of equipment number creation / modification.
It will only track changes to the reference number, and no other fields.
It does not track the value of the reference numbers, only whether or not it was changed.

select * from svc00310

or

SELECT        EQUIPID, LNITMSEQ, DATE1, TIME1, USERID, From_Customer_Number, To_Customer_Number, From_Serial_Number, To_Serial_Number, From_Item_Number, To_Item_Number, DSCRIPTN, DEX_ROW_ID
FROM            SVC00310
