A trigger is defined on a table. Only the table owner has create trigger and drop trigger permissions for that table; these permissions cannot be transferred to others.
SAP ASE accepts a trigger definition that attempts actions for which you do not have permission. The existence of such a trigger aborts any attempt to modify the trigger table because incorrect permissions cause the trigger to fire and fail. The transaction is canceled. You must rectify the permissions or drop the trigger.
For example, Jose owns salesdetail and creates a trigger on it. The trigger is designed to update titles.total_sales when salesdetail.qty is updated. However, Mary is the owner of titles, and has not granted Jose permission on titles. When Jose tries to update salesdetail, SAP ASE detects not only the trigger, but also Jose’s lack of permissions on titles, and rolls back the update transaction. Jose must either get update permission on titles.total_sales from Mary or drop the trigger on salesdetail.
