• What is the cause and solution for SAP error message /UI2/BASIS_UTIL107 - HTTP and HTTPS are using the same port for &1 ?

  The SAP error message /UI2/BASIS_UTIL107 indicates that both HTTP and HTTPS are configured to use the same port on the SAP system. This can lead to conflicts, as HTTP (typically port 80) and HTTPS (typically port 443) are expected to operate on separate ports to handle unencrypted and encrypted traffic, respectively.
  Cause:
  The primary cause of this error is a misconfiguration in the SAP system's Internet Communication Manager (ICM) settings. When both protocols are set to listen on the same port, the server cannot distinguish between HTTP and HTTPS requests, leading to this error message.
  Solution:
  To resolve this issue, you need to configure the ICM settings to ensure that HTTP and HTTPS are using different ports. Here are the steps to do this:
  
  
  Access the SAP GUI:
  
  Log in to your SAP system using the SAP GUI.
  
  
  
  Navigate to ICM Configuration:
  
  Use transaction code RZ10 to access the profile parameters.
  Alternatively, you can use transaction code RZ11 to check specific parameters.
  
  
  
  Check Current ICM Settings:
  
  Look for the parameters icm/server_port_0 (for HTTP) and icm/server_port_1 (for HTTPS).
  Ensure that they are set to different ports. For example:
  
  icm/server_port_0 = PROT=HTTP,PORT=80
  icm/server_port_1 = PROT=HTTPS,PORT=443
  
  
  
  
  
  Modify the Parameters:
  
  If both protocols are set to the same port, change one of them to a different port. For example, you could keep HTTP on port 80 and set HTTPS to port 443.
  
  
  
  Save and Activate Changes:
  
  After making the changes, save the profile and restart the ICM or the entire SAP system for the changes to take effect.
  
  
  
  Verify Configuration:
  
  After restarting, you can verify the configuration by checking the ICM logs or using transaction SMICM to see the active ports.
  
  
  
  Related Information:
  
  ICM (Internet Communication Manager): This is the component in SAP that handles HTTP and HTTPS requests. Proper configuration is crucial for web-based applications.
  Security Considerations: Ensure that HTTPS is properly configured with valid SSL certificates to secure data transmission.
  SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or updates related to this error message.
  
  By following these steps, you should be able to resolve the error message /UI2/BASIS_UTIL107 and ensure that your SAP system is correctly configured for both HTTP and HTTPS traffic.
