before you can start developing web dynpro applications you first have to activate several services in transaction SICF.

Have a look at note 1088717.

If you don't have any access to notes, please let me know.

Copy of the note:

Summary

Symptom

After you install the Application Server ABAP (AS-ABAP), all Internet Communication Framework (ICF) services are delivered as inactive (this is for security reasons). Following the installation you must decide, on an application-related basis, which services you must manually activate.

Other terms

ICF, Service, You are not authorized to view this page, RAISE_EXCEPTION, forbidden, error HTTP 403, Host is not active, Service is not active

Reason and Prerequisites

Since several services may be executed when you call a URL, you must activate all service nodes in the SICF tree. As a result, the URL path is represented in ICF subnodes (services). If, for example, you want to activate services for the URL/sap/public/icman, you must activate the service tree default_host in transaction SICF. You must then activate the individual services sap, publicand icman

You can activate an ICF service as follows:

1. In transaction SICF, select the ICF service in the ICF tree.

2. Use one of the following methods to activate the ICF service:

Use the menu option Service/Host -> Activate

Use the context menu and the entry Activate Service

If the default_host node is inactive in transaction SICF, the HTTP request may produce a "RAISE_EXCEPTION" ABAP runtime error

stating that the HOST_INACTIVE exception condition was triggered.

If a service is inactive in transaction SICF, the system displays the error text "Forbidden" when you access this service.

Solution

Services for Web Dynpro ABAP

For Web Dynpro ABAP (WDA), you must activate the following services in the system:

Using WDA applications

/default_host/sap/bc/webdynpro

Note that, in this case, you should activate only the node itself, not the subnodes.

/default_host/sap/public/bc

This node is automatically activated when you activate the subnodes described below. Similarly, in this case, you must activate only the node itself and the following subnodes:

- /default_host/sap/public/bc/ur

- /default_host/sap/public/bc/icons

- /default_host/sap/public/bc/icons_rtl

- /default_host/sap/public/bc/webicons

- /default_host/sap/public/bc/pictograms

- /default_host/sap/public/bc/webdynpro/* (ssr, mimes, and so on)

- /default_host/sap/public/myssocntl

In addition to these general WDA services, you still have to activate the relevant application services in the ICF tree. The service for the application <application> is generally located under the ICF node /default_host/sap/bc/webdynpro/sap/ <application>.

Using the WDA development environment

/default_host/sap/public/bc/webdynpro/viewdesigner

/default_host/sap/bc/wdvd/

The following five nodes are allowed to be active only in a development system, and under no circumstances in a production system (due to a security risk):

/default_host/sap/bc/webdynpro/sap/configure_application

/default_host/sap/bc/webdynpro/sap/configure_component

/default_host/sap/bc/webdynpro/sap/wd_analyze_config_appl

/default_host/sap/bc/webdynpro/sap/wd_analyze_config_comp

/default_host/sap/bc/webdynpro/sap/wd_analyze_config_user

WDA test applications for troubleshooting

/default_host/sap/bc/webdynpro/sap/wdr_test_events

/default_host/sap/bc/webdynpro/sap/wdr_test_ui_elements

/default_host/sap/bc/webdynpro/sap/wdr_test_table

/default_host/sap/bc/webdynpro/sap/wdr_test_adobe

/default_host/sap/bc/webdynpro/sap/wdr_test_popups_rt

Other services

Support for the Internet protocols (HTTP, HTTPS and SMTP) in the AS-ABAP

/default_host/sap/public/icman

After you install AS-ABAP, you must ensure that this service is activated in transaction SICF. As a result, the ICM may (for example) make decisions concerning the distribution of HTTP requests to the relevant server.

Using the load distribution

with the message server

- /default_host/sap/public/icf_info

- /default_host/sap/public/icf_info/logon_groups

- /default_host/sap/public/icf_info/urlprefix

with the SAP Web Dispatcher

- /default_host/sap/public/icf_info

- /default_host/sap/public/icf_info/icr_groups

- /default_host/sap/public/icf_info/icr_urlprefix

ICF test applications:

/default_host/sap/bc/echo

Among other things, this service returns information about the registration procedure being used, the header and form fields, and the generated SSO cookie for the executed request. Therefore, this service should only be activated for troubleshooting purposes.

/default_host/sap/bc/error

This service generates some error situations in the system and you should activate it only for troubleshooting purposes.

Go to transaction SICF and activate the services mentioned above.

Mark a note, right click on mouse and select activate service.

Good luck.
