The Simple SCRUD option in a business object's Common Activities tab automatically generates all the parts of a fully functional business object: a hidden filter, a command handler and a server module which allow the table associated with the business object to be searched and maintained.
The simple SCRUD is meant to be used with business objects associated with simple database tables containing a relatively small number of rows.
The acronym SCRUD refers to the basic manipulation of the available data the user needs to work with: Search, Create, Read, Update and Delete.
SCRUDs are often used to rapidly mass-produce maintenance functions for 'code' tables like currencies, countries, states, zip codes, etc.
