  The SAP error message CM_SDM_API025 indicates that there was an issue when the system attempted to read from the database cache. This error can occur in various scenarios, often related to issues with the database connection, cache corruption, or configuration problems.
  Causes:
  
  Database Connection Issues: The connection to the database may be interrupted or misconfigured, leading to read failures.
