Once you have installed the Application Server ABAP (AS ABAP) all Internet Communication Framework (ICF) services are available in an inactive state for security reasons. After the installation you have to decide which services must be activated for the applications you want to use.
Since multiple services can be executed when you call a URL, all service nodes must be activated in the SICF tree. The URL path is mapped in ICF subnodes (services). For example, if you want to activate the services for URL /sap/public/icman, you have to activate the service tree default_host in transaction SICF. Then you have to activate services sap, public and icman separately.
You activate an ICF service as follows:
...
1. Select the required ICF service in the ICF tree in transaction SICF.
2. Activate the ICF service in one of the following ways:
a. Using menu option Service/Host → Activate
b. Using the context menu and choosing Activate Service.
If the default_host node is inactive in transaction SICF, the HTTP requests could result in ABAP runtime error RAISE_EXCEPTION with the following short text:
Exception condition "HOST_INACTIVE" triggered.
If a service is inactive in transaction SICF, an error text appears when you try to access the service.
You can also use report RSICF_SERVICE_ACTIVATION to activate a predefined group of ICF nodes. When you run this report you can select the following predefined groups (technical names):
● WEB DYNPRO ABAP
● WEB DYNPRO ABAP DESIGN TIME
Group for Web Dynpro ABAP development. Note that this setting is not supported for productive operation.
● WEB DYNPRO ABAP TEST APPS
Group for test applications. Note that this setting is not supported for productive operation.
For Web Dynpro ABAP (WDA) the following services must be activated in the system.
/default_host/sap/bc/webdynpro
Here only the node itself must be activated, and not the subnodes.
/default_host/sap/public/bc
This node is activated automatically when the subnodes described below are activated. Likewise, here only the node itself must be activated, as well as 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, etc.)
/default_host/sap/public/myssocntl
In addition to these standard WDA services the relevant application services must also be activated in the ICF tree. Usually, the service for application <application> can be found under the ICF node /default_host/sap/bc/webdynpro/sap/<application>.
/default_host/sap/public/bc/webdynpro/viewdesigner
/default_host/sap/bc/wdvd/
The five ICF nodes below are needed only for the WDA environment. They are only allowed to be active in a development system, and on no account in a production system, as this poses 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
/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
/default_host/sap/public/icman
Once AS-ABAP has been installed, you must ensure that this service is activated in transaction SICF. This enables the ICM to decide how HTTP requests are distributed to the servers.
● Using the message server
○ /default_host/sap/public/icf_info
○ /default_host/sap/public/icf_info/logon_groups
○ /default_host/sap/public/icf_info/urlprefix
● Using 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
The following services are for internal SAP use only:
● /default_host/sap/bc/echo
This service provides information about the logon procedure in use, header and form fields, and the SSO cookie generated for the processed request. For this reason this service must only be activated for error analysis.
● /default_host/sap/bc/error
This service creates some error situations in the system and should only be activated for error analysis.
