  Performance Bottlenecks: The middleware or the receiving system may be experiencing performance issues, leading to delays in processing the transferred data.
  Error in Data: There may be issues with the data being transferred, such as missing or incorrect information that prevents successful processing.
  
  Solution:
  
  Check Middleware Configuration: Ensure that the middleware is correctly configured to receive and process data from APO. Review the communication channels and mappings.
  Monitor Performance: Use monitoring tools to check the performance of the middleware and the receiving system. Identify any bottlenecks and optimize them.
