Hmmmm...It is in my SO_Invoice_bus in all three environments that I've tested. Right next to the Pre Delete sub. I tried it on MAS 90 4.40.8, MAS 90 4.50.0 and MAS 200 SQL 4.5.2. All three generate ONLY the pre delete event, and none generate the post delete. I get the ""are you sure"" prompt, but nothing after that. I wonder what else cold be different? I'll try it on my 4.40.6 MAS 200. Thanks for the feed back! (Again)
