The Internet Communication Manager (ICM) enables communication between your SAP system and the Internet using the HTTP or HTTPS protocols for the NWBC applications. NWBC (both the shell and most content area types) uses HTTP to access an ABAP server. It is important that at a minimum one HTTP or HTTPS port is configured and active.
From the back-end system, go to the ICM Monitor ( SMICM) transaction.
Chooseto display the services configured in ICM.
The following figure shows an example of services in ICM Monitor :
If the HTTP or HTTPS service does not yet exist or you would like to make changes, you can create or edit a service by choosingor in the menu.
Enable or modify the HTTP or HTTPS port settings, if necessary.
Activate your HTTP or HTTPS service by choosing.
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>.
A Web dispatcher can be placed before the AS ABAP system(s) to function as a reverse proxy. The Web dispatcher is then normally configured to access the server through HTTPS (for higher security) and to forward all data to the server through 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 .
