Passing Parameters via Web Dynpro Application

Transcription

1 Applies to: SAP ABAP Workbench that supports Web Dynpro development. For more information, visit the Web Dynpro ABAP homepage. Summary This article explains how to pass parameters via Web Dynpro Application. In general, data can be shared via context of different controller only in the same session (i.e. in the same web page) but data cannot be shared between two different sessions (i.e. two different web pages). So to pass the data between two different sessions, we pass data through the web Dynpro Application (URL).

3 PRE-REQUISITES: Basic knowledge in Web Dynpro ABAP concepts like context mapping and calling the web dynpro component using external window. BASIC INFORMATION: Generally, we use context mapping for sharing data between the views of same component or different components. Data can be passed via context only in a same session but data cannot be passed or accessed between different sessions via context mapping. For accessing the data between the different sessions, we have to pass parameters via Web Dynpro Application (URL). REQUIREMENT: Display the list of materials in the application 1 and then display the sales item details of the selected material in the new page (new session) COMPONENT CREATION: 1. Create a Component YSG_MATERIAL with a view and a window and embed view to the respective window. a. View 1 : V_Main Window 1 : W_Main 2. Create a node MATERIAL with cardinality 0-n and design layout with a table in the MAIN view. 3. Implement logic in WDDOINIT( ) to display list of materials in the table, when the application is called 4. Activate and execute the application 3

4 5. Create component YSG_SALES with a view and a window. a. View: V_MAIN Window: W_MAIN 6. Create node SALES in the component controller with the cardinality Define context mapping with the node sales in V_MAIN and W_MAIN View Window 4
