  The SAP error message /IWFND/MED037 Metadata cache (cluster table) was cleaned up by user '&1' typically indicates that the metadata cache for the OData services has been cleared or cleaned up by a user. This can happen for various reasons, such as manual intervention, system maintenance, or automated processes.
  Cause:
  
  Manual Cleanup: A user may have manually triggered the cleanup of the metadata cache, either through transaction codes or specific administrative actions.
  System Maintenance: Regular maintenance tasks or scripts may be set up to clear the cache periodically to ensure that the system runs optimally.
  Development Activities: During development or testing, developers might clear the cache to ensure that changes to OData services are reflected immediately.
  Performance Optimization: Sometimes, clearing the cache is done to resolve performance issues or to refresh the data after significant changes.
  
  Solution:
  
  Check User Activity: Identify the user who performed the cleanup (as indicated by &1 in the message) and verify if this action was intentional.
  Rebuild the Cache: If the cache has been cleared, the system will automatically rebuild it as OData services are accessed. There is usually no need for manual intervention unless there are issues.
  Monitor System Performance: After the cache is cleared, monitor the system performance to ensure that it is functioning as expected.
  Review Maintenance Jobs: If the cleanup was not intentional, review any scheduled jobs or maintenance tasks that might be set to clear the cache.
  Educate Users: If users are clearing the cache without understanding the implications, consider providing training or guidelines on when and how to perform such actions.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes related to OData services and cache management, such as /IWFND/MAINT_SERVICE for managing OData services.
  SAP Notes: Check for any relevant SAP Notes that might provide additional context or solutions related to cache management and OData services.
  System Logs: Review system logs for any additional messages or errors that might provide more context around the cache cleanup event.
  Performance Tuning: Consider implementing performance tuning measures if cache clearing is a frequent occurrence that impacts system performance.
  
  In summary, while the message indicates that the metadata cache has been cleared, it is generally a normal operation that the system can handle. However, understanding the context and ensuring that it aligns with operational practices is essential for maintaining system stability.
