How to Create WebDynpro Value Help using CAF Entity Service Method

Applies to: SAP NetWeaver 2004s (SP7, SP8 and SP10) Web Dynpro for JAVA and CAF.

Summary This document explains how to create Web Dynpro value help using CAF entity service methods. First we will create a Composite Application with Entity Service methods and then we will create a Web Dynpro project using CAF Web Dynpro model and also the presentation logic inside the Web Dynpro Project. But some times Entity Services do not fulfill our business logic requirement; In that case we can write our own custom business logic in side different types of Custom Application methods like “Custom”,” Access” (Create, Read, Update, and Delete), “Queries” or “BW Extractor” according to our requirement and create value help using those Application Service methods.
