The Basic Notification requires that you have already created your own buffer table to hold the notification rows, and a trigger to create those rows. The other operations create those things for you.
I highly recommend that you read the section on these operations in the Developer’s Guide (or Database Adapter Guide, if using webMethods 4.x/5.x). More explanation is available there.
