• What is the cause and solution for SAP error message SWL_WP047 - Network number of IP address "&" is greater than 223 ?

  The SAP error message SWL_WP047 indicates that there is an issue with the network number of an IP address being greater than 223. This typically relates to the way IP addresses are categorized and used in networking.
  Cause:
  The error arises because the IP address being processed has a network number that exceeds the valid range for certain types of IP addresses. In IPv4, the first octet of an IP address determines its class:
  
  Class A: 1 to 126
  Class B: 128 to 191
  Class C: 192 to 223
  Class D: 224 to 239 (used for multicast)
  Class E: 240 to 255 (reserved for future use)
  
  The error message suggests that the IP address being referenced has a first octet greater than 223, which means it falls into Class D or E, and is not suitable for standard host addressing.
  Solution:
  
  
  Check the IP Address: Verify the IP address that is causing the error. Ensure that it is correctly formatted and falls within the valid range for the intended use (Class A, B, or C).
  
  
  Correct the Configuration: If the IP address is incorrectly configured in the SAP system or in the network settings, update it to a valid address. This may involve:
  
  Changing the IP address in the SAP configuration.
  Updating network settings in the operating system or network devices.
  
  
  
  Review Network Settings: Ensure that the network settings in your SAP system are correctly configured to use valid IP addresses. This includes checking any relevant configuration files or settings in the SAP GUI.
  
  
  Consult Documentation: If you are unsure about the correct IP address to use, consult your network administrator or refer to SAP documentation for guidance on network configuration.
  
  
  Testing: After making changes, test the connection or functionality that was previously failing to ensure that the issue has been resolved.
