  Causes:
  
  Invalid WSDL File: The WSDL file may be malformed or not conforming to the expected structure.

  Review Network Settings: Check network configurations and firewall settings to ensure that the SAP system can access the WSDL if it is hosted externally.
  Update WSDL: If the WSDL is outdated or incompatible, consider updating it to a version that is compatible with your SAP system.
