Integrating ALV into your Web Dynpro Application 
SAP List Viewer (ALV) is available to you as a Web Dynpro component which you can integrate into a Web Dynpro component of your application.
You can embed the ALV into your Web Dynpro component like any other Web Dynpro component however there are a few things to take into consideration.
You must have exeucted the following (ALV-independent) steps:
You have created a Web Dynpro component for your application and saved it actively
You have created a context node with the cardinality 0..n. The structure of the attributes in this context node (name and data type) matches those in the internal data table that you connect to this context node.
Define a component usage so that the ALV component (SALV_WD_TABLE) is available to you.
For more information: Defining ALV Component Usage
You map the data of your Web Dynpro component with the context node DATA of the ALV component.
For more information: Providing Data
You embed the TABLE view of ALV component into an appropriate position in one of your views.

You can use the ALV now with its standard settings but you do not have any further configuration options.
To be able to configure the ALV, use the ALV Configuration Model.
