The original way in IFS Applications (Apps9 and earlier) required configuration of History Logging beforehand, and a IAL/custom select & Quick Report to fetch results from History Log and History Log Attribute. 

Now I suppose you would create a Custom LU and a Custom Trigger to insert a row into the Custom L:U upon Delete of a row form the Shop Order object. 

Sorry I can’t be definitive about Apps10 capability. 

@bverdera Another option would be to create a Custom Event on shop_ord_tab on delete (Objects are removed). Then simply create an Event Action on top of the newly created Custom Event with Action Type email and you should be done.
