Generic class for inserting, updating and deleting records
Purpose of this class is to store and process records that need to be modified in database tables. When the user is working on an object that contains header and detail records, a 'Save' means that records need to be modified in different tables. Imagine that the application shows a grid where the user can insert, update and delete records; the logic for saving these changes can be a bit complex.
This class should provide the necessary functions for this kind of functionality. It holds a table with the database tables and records that we need to update. Methods are available to add entries to this table and this means that during a process, the required database updates are collected until the actual database update takes place. When the application has finished the process, it calls the method that performs the database update.
Advanced and Generic Programming in ABAP
Session from SAP TechEd '04 -- Shows you how to add dynamic elements to your ABAP programs and make them more flexible with regard to changing requirements. You will learn how to write generic services that can deal with dynamically structured data that was unknown at design time. Also, a brand- new Dynamic Type Creation tool enables you to create types on-the-fly, without the need for program generation.
