This error can occur during the integration of APO with other systems, such as SAP ERP or third-party applications.
  Cause:
  
  Data Transfer Issues: The error may arise due to problems in the data transfer process between APO and the middleware. This could be due to network issues, configuration errors, or data inconsistencies.
  Configuration Errors: Incorrect configuration of the product substitution schema in APO can lead to this error. This includes missing or incorrect settings in the substitution rules or schemas.
  Middleware Configuration: If the middleware is not properly configured to handle the data being sent from APO, it may result in errors during the transfer.
  Performance Issues: The duration mentioned in the error message may indicate that the process is taking longer than expected, possibly due to performance bottlenecks in the system.
  
  Solution:
  
  Check Configuration: Review the configuration of the product substitution schemas in APO. Ensure that all necessary settings are correctly defined and that there are no missing entries.
  Monitor Middleware: Check the middleware configuration and logs to identify any issues that may be causing the data transfer to fail. Ensure that the middleware is set up to handle the data being sent from APO.
  Network and Performance Monitoring: Investigate any network issues that may be affecting the data transfer. Additionally, monitor system performance to identify any bottlenecks that could be causing delays.
  Error Logs: Review the error logs in both APO and the middleware for any additional error messages or warnings that could provide more context about the issue.
  Testing: Conduct tests to replicate the issue and identify the specific conditions under which the error occurs. This can help in pinpointing the root cause.
