HTTP/HTTPS Settings in the ICM

The Internet Communication Manager (ICM) enables communication between your SAP system and the Internet using the HTTP or HTTPS protocols for the Business Client applications.

NWBC (both the shell and most canvas types) uses HTTP to access an ABAP server. It is important that at a minimum one HTTP or HTTPS port is configured and active.

1. From the backend system, call transaction SMICM (ICM Monitor). Navigate to  Goto  Services  to display the services configured in the ICM
    (Example of services in SMICM)
2. If the HTTP or HTTPS service does not yet exist or you would like to make changes, you can create or edit a service via  Service  Create  or  Service  Change  in the menu.
3. Enable / modify the HTTP or HTTPS port settings, if necessary.
4. Make sure your HTTP or HTTPS service is active via  Service  Activate .

 Caution

Note that any changes you make here are lost when you restart. If you want to create or change a service permanently, you must do this using the profile parameter icm/server_port_<xx>.

SAP Web Dispatcher

A Web Dispatcher can be placed before the AS ABAP system(s) to function as a reverse proxy. In such cases, it is typical that the Web Dispatcher is configured to the one option only to access the server via HTTPS (for higher security) and to forward all data to the server via HTTP (for higher performance). In these scenarios, pay special attention to the configuration of the HTTPURLLOC table in accordance with the information in URL Generation in an AS-ABAP - Web Dispatcher Configuration.
