Summary :
The SAP Note addresses an issue where system logs in the backend (SM21) report "ICM_HTTP_CONNECTION_FAILED" errors and advises this is only pertinent within Business Warehouse Accelerator (BWA) or Enterprise Search (ESH) scenarios. The note outlines unnecessary ICM configurations as the root cause in instances unrelated to BWA or ESH. To mitigate these errors, users are suggested to reference SAP Note 1246275, adjust SICF proxy settings, update the /etc/hosts file with accurate TREX server information, and ensure no firewall blocks exist on indexserver ports used by the application servers.
