• What is the cause and solution for SAP error message SR202 - Only use numerical values for port (or service) ?

  The SAP error message SR202, which states "Only use numerical values for port (or service)," typically occurs when there is an issue with the configuration of network settings, particularly when specifying a port number or service name in a configuration file or during a setup process.
  Cause:
  
  Non-Numeric Input: The most common cause of this error is that a non-numeric value (such as a string or special character) has been entered in a field that expects a numerical port value.
  Incorrect Configuration: The configuration file or settings may have been incorrectly edited, leading to invalid entries.
  Service Name Instead of Port Number: Sometimes, users might mistakenly enter a service name (like "http" or "ftp") instead of the corresponding port number (like 80 or 21).
  
  Solution:
  
  
  Check Configuration: Review the configuration settings where the port number is specified. Ensure that only numerical values are entered. For example, if the port number is supposed to be 8080, make sure it is entered as "8080" and not "http" or any other string.
  
  
  Use Valid Port Numbers: Ensure that the port number is within the valid range (0-65535). Common ports include:
  
  HTTP: 80
  HTTPS: 443
  FTP: 21
  Custom applications: Check the documentation for the specific application.
  
  
  
  Edit Configuration Files: If the error arises from a configuration file (like instance profile or SAP GUI settings), open the file in a text editor and look for the port settings. Correct any non-numeric entries.
  
  
  Restart Services: After making changes, restart the relevant SAP services or the entire SAP system to ensure that the changes take effect.
  
  
  Consult Documentation: If you are unsure about the correct port numbers or configuration settings, refer to the SAP documentation or the specific application documentation for guidance.
