Now about when to use ?

Situation where you need to develope Custom Developement for Client with SAP you can use WebDynpro . Just take case that client want that his some business process to be automised over web then we will go for WebDynpro .Eg. Let client want that his shopfloor worker should be able fill BOM , Q-form over web .For that some web site adress (URL ) will be give to him . He can fill that data from anywhere just need to have browser . So by WebDynpro your SAP will be completely aviiable over Web .

Not just that it seems that future will be WebDynpros.

Hi Sanmugam,

Welcome to Web Dynpro ABAP !

In web dynpro ABAP we follow MVC(Model View Controller) architecture.

In this object oriented ABAP is used to provide background functionality. Here, your ABAP skills can be utilized to the fullest. Programming in web dynpro ABAP is different than conventional ABAP programming. Here we strictly follow MVC architecture in terms of controller interface. Also there are many wizards available so that we can directly pick the code from wizards.

e.g We can call BAPI through a service call in web dynpro application. Thus automatically backgroud code for BAPI execution will be generated.

To start with Web dynpro ABAP you can try following tutorial:

https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a282c952-0801-0010-1eb5-87953e03...

You can start with tutorials and all. There are around six tutorials in SDN library.

and now about WD ABAP

1) Web Dynpro ABAP

As the name suggests Web Dynpro for ABAP uses exactly the same meta model as its cousin Web Dynpro for Java. A Web Dynpro component, a Web Dynpro view, a Web Dynpro model, a Web Dynpro controller have the same semantics both for ABAP and Java. The main difference is the designtime environment, the development infrastructure and the runtime environment.

The designtime environment is properly embedded in the ABAP Workbench where Web Dynpro artifacts are simply a new category like BSP applications or classical dynpro based applications before. Also no surprises regarding the development infrastructure. The correction and transport system keeps track on all changes that are done, versions them and helps to propagate the Web Dynpro application from development to production like you would do with ordinary BSP or dynpro-based applications.

Last not least the execution platform is the ABAP server that produces application content ready to be integrated in the NetWeaver Portal seamlessly. Features like portal eventing can be used between applications written in ABAP or applications developed with Java.
