7/28/2019 17.4- WDA Training - Day 4


Hands-On - Dynamic Programming


Dynamic Layout Manipulation - Under certain conditions, it may be useful tochange the layout of a view at runtime, e.g., CL_WD_UIELEMENT_CONTAINER

(methods add_child(), get_child(), remove_child()) and CL_WD_BUTTON, etc

Working Dynamically with Parameter Mappings - The term parameter mapping

is used for the bind of an event parameter to a parameter of an action handler

method

Dynamic Context Manipulation - You can manipulate the context of a controller

in different ways at runtime, e.g., IF_WD_CONTEXT_NODE_INFO

(ADD_NEW_CHILD_NODE)

Working Dynamically with Component Usages

Dynamic embedding of an Interface view into a window

SAP Recommendation - you should use the dynamic manipulation of the

layout and context – only if it is not possible to construct a component by

declarative means

Integration with Portal


SAP Web Dynpro ABAP iView template

Portal manager IF_WD_PORTAL_INTEGRATIONPortal Events (client side eventing)

Register WDA application for portal events

Trigger portal events

Portal Navigation – a WDA application can navigate to ITS or BSP

application or another WDA application

Absolute navigation

Relative Navigation

Object based navigation - Instead of defining a concrete target

URL, you call a particular operation of a particular Business Object.

Work Protect mode

Component and Application configuration


Configuration and Personalization – two ways of changing the UI of SPAstandard screens

Configuration – design time

Component Configuration – create configuration data records for

individual Web Dynpro components. This can be explicit or implicit

Application Configuration – defines which component with which

configuration is required for the Application

Personalization–

run timeUser Personalization – available only for that user

Administrator Personalization (Customization) – available for

large group of users
