New to WDA

[sap_cohort]

Hi, I'm new to WDA and looking to write a test app to just list out Process Chain Groups and the related process chains. Can anyone suggest some existing code I might be able to use to get started? Or even a basic tutorial that might show me how to produce a list of something that could be clickable by a user?

Thanks,

Hi Ken,

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.

hi ,

1) This is basic Info of WD 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.

2 ) I can give you links that can help you a lot.

First of all start doing SAP SDN tutorials .

Create some compenents with BAPI , Component usage and ALV .

/people/marilyn.pratt/blog/2005/12/20/web-dynpro-for-abap

Try to Download demo tutorials from SDN library & Try to search WebDynpro ABAP WebLogs .

Wait not just that SAP has provided you with ample demo example of WD ABAP already bundled with SAP . Just Try out Components starting with WDR . I can tell you few like WDR_TEST_EVENTS ( It shows how every UI elments to use )

See packages like SWDP_DEMO , SALV_WD_DEMO

there are many more .

Hope I have helped you .
