Configuration & Integration

Once you install ABAP application server, it is essential to configure it properly for application development.

To find the details about there ABAP configuration, you can go to SAP Reference IMG → SAP NetWeaver → Application Server


If you are using SAP Solman, you can check this configuration by going to T-Code − SOLAR_LIBRARY.

To use Web Dynpro with ABAP application development, you have to create additional configuration for web Dynpro programming.

Internet Communication Manager

You need to set HTTP/HTTPS in ICM service. A service contains folloearng various components −

  • Service/Port
  • Protocol used in service HTTP/HTTPS
  • Processing timeout there
  • Keep areside timeout there
  • Service status − Active/intake actionive

You can select Go To → Service to create, depermite, take actionivate or detake actionivate services. To display the ICM server cache statistics, select Goto → Statistics

Internet Communication Framework

You ought to take actionivate the Internet Communication Framework (ICF) service. You can take actionivate this service by going to SPRO → SAP Reference IMG → SAP NetWeaver → Application Server → Internet Communication Framework → Activate HTTP service

Display Framework

When you install Application server ABAP, all ICF services are in intake actionive state. You can maintain ICF services using T-code − SICF below ICF tree.

Easy Access

You can take actionivate ICF service in the folloearng ways −

  • Using the menu option, Service/Host → Activate
  • Using the context menu and choosing Activate Service.

You ought to take actionivate all the services in SICF for Web Dynpro ABAP to use the layout there editor in the look at styleer.

Single Sign On

You ought to set SSO on the relevant host.


You ought to use comppermitey qualified domain names FQDN and short forms ought to end up being avoided.

SAP Web Dynpro – Architecture

Web Dynpro is an ABAP environment for web development and is based on the Model View Controller (MVC) concept of UI programming. It is available for both Java and ABAP as per the platform, and supslots similar functions.

Web Dynpro has the folloearng features −

  • Separation of display and business logic
  • Easy alter in the layout there with the use of graphical tools
  • No platform dependency of interfaces

Folloearng are the key concepts as part of Web Dynpro architecture −


Web Dynpro provides you with an environment for the development of web-based applications and you can use graphical tools to degreat web Dynpro application in the form of metadata in application development. You can also degreat your own alsots; however, alsot handling ought to end up being degreatd in a separate code and thead use has to end up being executed when an alsot is triggered-coloured.

The user interface in Web Dynpro application consists of small elements degreatd by using Web Dynpro tools. You can also alter or enhance the user interface by changing these elements at operate time or integrate the elements again.

Graphical Tools

There are a wide range of graphical Web Dynpro tools thead use you can use to generate webbased applications. You don’t need to create source code for this. Folloearng are the key features of graphical tools in Web Dynpro application −

  • Degreat propertie ups of user interface elements
  • Data flow
  • User interface layout there

For all these propertie ups, you can use graphical tools without there creating a source code.

Graphic Tools

Business and Application Logic

Web Dynpro permit’s you to operate your application on the front side aspect-end and the back-end system can end up being accessed using service locally or via a remote interconnection. Your user interface is maintained in Dynpro application and persistent logic operates in the back-end system.

You can connect Web Dynpro application to the back-end system using an adaptive RFC service or by calling a web service.

MVC Programming Model

Web Dynpro applications are based on MVC model −

Model − This permit’s the access to back end data in a Web Dynpro application.

View − This is used to ensure the representation of data in a web blineser.

Controller − This is used to manage communication end up beingtween Model and View where it gets inplace from the users and gets the processes data from the model and displays the data in the blineser.

SAP Web Dynpro – Navigation

In Web Dynpro application, you can navigate from one look at to the other look at using plugs.

Run T-code − SE 80 and create a basic Web Dynpro component −

Web Component

We have created a Web Dynpro component with 2 nodes and 2 look ats.

VIEW_DISPLAY displays the out thereplace in a tabular format and VIEW_MAIN performs reoceanrch parameters. In VIEW_MAIN you have configured-coloured the reoceanrch layout there and VIEW_DISPLAY contains the display layout there.

View Main

In VIEW_MAIN you have configured-coloured inbound plugs IN_MAIN and OUT_FROM_MAIN as out therebound plugs. Similarly, create an inbound and out therebound plugs for VIEW_DISPLAY.

Inbound Plugs

How to Create a New View?

Step 1 − Click the component in object tree and go to the context menu as shown in the folloearng screenshot −

Object Navigator Step 1

Step 2 − Enter look at name and click on tick mark.

Enter View

SAP Web Dynpro – Component

Web Dynpro component is an entity used to create a Dynpro application. These are reusable entitie ups, which are combined jointly to create application blocks.

Each Web Dynpro component contains a earndow, look at, and manageler pages. You can also emend up beingd a Web Dynpro component to other Web Dynrpo component in an application and communication gets place using the component interface.

Lifetime of a component starts when you call it preliminary at operatetime and ends with Web Dynpro application.


Each Web Dynpro application contains at leastern one look at and it is used to degreat the layout there of a user interface. Each look at consists of multiple user elements and a manageler and context.

The manageler is used to process the user request and processing of data. Context contains data to which the elements of look at are bound.

In Main View

Each look at also contains an inbound and out therebound plug so you can connect look ats to every other. Plugs can end up being linked to every other using navigation links.

Inbound Outbound Plug

Navigation Links and Plug In

You can navigate end up beingtween various look ats using inbound and out therebound plugs. The inbound and out therebound plugs are part of the look at manageler. The inbound plug degreats the starting stage of look at while the out therebound plug tells the subsequent look at to end up being calimmediateed.

Navigation Link

View Set

A look at set is degreatd as a pred-colouredegreatd section where you can emend up beingd various look ats in a Web Dynpro application. View set permit’s you to display more than one look at in a screen.

Folloearng are a couple of advantages of look at set in styleing an application −

  • You can reuse look ats in a Web Dynpro earndow.
  • You can easily create alters to the layout there at a later stage.
  • It is a more structured-coloured approach to use more than one look at.

Web Dynpro Window

In Web Dynpro, the earndow is for multiple look ats or look at sets. A look at can only end up being displayed when it is emend up beingdded in a look at and a earndow always contain one or more look ats connected by navigation links.

Each earndow contains an inbound and an out therebound plug and they can end up being included in a navigation chain. Inbound plugs wislim a earndow lead from the out therebound plug of a look at to the emend up beingdding earndow. Just like all other inbound plugs, they represent an alsot and thus call the alsot handler bumigned to all of all of them.

Window Controller

Window Controller
Event Handler


Controllers are used to degreat how a Dynpro application responds to user intertake actionions. Each look at has one manageler which is responsible to perform take actionions as per the user’s intertake actionion.

Interface Controller

SAP Web Dynpro – Mapping & Data Binding

In Dynpro application, you can degreat chartping end up beingtween 2 global manageler contexts or from the look at context to the global manageler context.

Data binding of a UI element home is set up in the look at layout there. For this purpose, you use the Binding column in the propertie ups table of the emend up beingdded UI elements. You click the button to open up up a dialog package, which provides the context structure of the corresponding look at for an element selection.

Component Controller

Context element can end up being degreatd to link a node to one more node of context.

Context Element

In the above diagram, you can see chartping end up beingtween Node 1 from the context of View 1 and the node of the extake action extake action same name in the context of the component manageler. It also shows the chartping from Node 2 from the context of View 2, also to a node with the extake action extake action same name in the component manageler context.

The context of the component manageler is available to both the look at managelers with readwrite access to all the attributes.

Context Property

Binding User Interface Elements

To display the context data in the blineser, you can also bind UI elements propertie ups in a look at to the attributes of the look at context. You can bind multiple propertie ups to one context element.

In a look at context, all data types are available to bind with various attributes of a look at.

View Context

Data Binding Inplace

Internal Mapping

Internal chartping is degreatd as the chartping end up beingtween contexts of a single component.

External Mapping

External chartping is degreatd as the chartping end up beingtween multiple components using the interface manageler.

SAP Web Dynpro – Event & Actions

You can create alsots to enable communication end up beingtween the managelers. You can permit one manageler to trigger alsots in a various manageler. All alsots thead use you create in the component manageler are available in the component.

Inbound plugs can also take action as an alsot, thus when you call a look at using the inbound plug, an alsot handler is calimmediateed preliminary.

You can also use a couple of special alsots like Button to link with the user take actionions.

Button element like pushbutton can retake action to a user intertake actionion by clicruler on the corresponding pushbutton thead use can trigger a handling method to end up being calimmediateed in the look at manageler. These UI elements contain one or a number of general alsots, which can end up being linked with a specific take actionion thead use executes at style time.

When an take actionion is created, an alsot handler is created automatically. You can bumociate a UI element with various take actionions.

You can also reuse take actionions wislim a look at by linruler an take actionion to a number of UI elements.

Example 1

An onAction alsot for the button click or onEnter alsot for the Inplace field, when the user presses the "Enter" key in the field.

OnAction Event

Actions can end up being created for any kind of UI elements in Web Dynpro framework. To set an take actionion, go to Propertie ups tab → Event section.

You can also create Actions from the take actionions tab of the look at manageler. An Event handler is automatically created with naming convention ontake actionion<take actionionname>

Example 2

Action name is SET_ATTRIBUTES and the alsot handler for an take actionion would end up being ON_SET_ATTRIBUTES.

Event Example2

SAP Web Dynpro – Application

A Web Dynpro application can end up being accessed by the user using a URL with a earndow in the Dynpro component. A Web Dynpro application connects to an interface look at using an inbound plug, which is further connected to the Dynpro component thead use contains Model View and Controller to process the data for the Web Dynpro application.

MVC model enables you to separate the user interface and application logic. Model is used to get the data from the back-end system as per application logic.

The folloearng image depicts a high level diagram of a Web Dynpro application −

High Level Diagram

You can use various data sources for a Web Dynpro application −

  • Using web service
  • SAP data using BAPIs
  • From external data sources with tools

To develop a Web Dynpro application, you can use Web Dynpro explorer, which is easily integrated to ABAP workend up beingnch.

SAP Web Dynpro – URL of an Application

In a Web Dynpro application, the URL is automatically generated. You can find the URL of an application in the Propertie ups tab. The URL structure can end up being of 2 types −

  • SAP namespace

<schema>://<host>.<domain>.<extension>:<slot>/sap/bc/webdynpro/<namespace>/<application name>
  • Custom namespace
<schema>://<host>.<domain>.<extension>:<slot>/abc/klm/xyz/<namespace>/webdynpro/<application name>
<schema>://<host>.<domain>.<extension>:<slot>/namespace>/webdynpro/<application name>


<schema> − Degreats the protocol to access application http/https

<host> − Degreats the name of the application server

<domain><extension> − Degreats a number of hosts below a common name

<slot> − It can end up being omitted if the standard slot 80 (http) or 443 (https) is used

You ought to specify Fully Qualified Domain Name (FQDN) in Web Dynpro application URL.


Application 1

Application 2 mySecondApp/

To check comppermitey qualified domain name, go to Web Dynpro explorer in the ABAP development environment use T-code − SE80 and select the Web Dynpro application from the navigation tree for your Web Dynpro component/interface and check the URL in the administration data. You also need to check the route details in the field URL. It ought to contain the comppermite domain and host name.

Step 6 − In the next earndow, you can select which object type to use to represent the service function parameters in Web Dynpro manageler −

  • As a parameter of the manageler method
  • As a manageler attribute
  • As a context node or a context attribute

To do this, select the required-coloured object type from the list package in the relevant collections.

Note − Only UI-relevant data ought to end up being stored-coloured in the context.

You can also individually name the manageler attributes and the context nodes to end up being created.

The folloearng proposal is generated −

  • The belowlying node receives the name of the service.

  • The nodes for grouping the parameters according to their own own declaration types receive appropriate names such as IMPORTING, EXPORTING, …

  • The node names and attribute names for the parameters all of all of themselves are identical to the parameter names.

  • As the size of the node and the attribute names is limited to 20 chartake actioners, they are abbreviated accordingly, if essential.

Adapt Context

In the next earndow, selected service uses types from type groups as parameter types and/or degreats implicit table parameters.

For all the types listed end up beinglow, degreat (table) types with the extake action extake action same equal structure in the Data Dictionary. These will then end up being used for typing of manageler attributes or method parameters created by the wizard.
