I would create an Operator under SQL Server Agent in SQL and use Database Mail to set up an email account and create a SQL script to look for new POs. I set up email alerts to for the activity, sy00800,sy00801 and dex locks and sessions tables. eMails get sent to myself and the clients GP admins. This way they can be proactive is seeking out potential problems.
Here is a portion of those scripts:
IF EXISTS (SELECT TOP 1 [USERID],[CMPNYNAM],[LOGINDAT] FROM [dbo].[ACTIVITY])
SET @CURRENTACTIVITY = 1
IF @CURRENTACTIVITY = 1
BEGIN
-- Generate user activity email
EXEC msdb.dbo.sp_send_dbmail
@profile_name = 'COMPANY eMail',
@recipients = 'donaldduck@cartoon.com;mickeymouse@cartoon.com',
@query = 'USE DYNAMICS;
GO
SELECT [USERID],[CMPNYNAM],[LOGINDAT] FROM [dbo].[ACTIVITY] ORDER BY USERID
GO',
@subject = '**** ERROR - Current Activity ****',
@body='Current users logged into GP',
@attach_query_result_as_file = 1;
END
