• What is the cause and solution for SAP error message RSDD804 - Check for aggregate &1 terminated unexpectedly ?

  The SAP error message RSDD804, which states "Check for aggregate &1 terminated unexpectedly," typically occurs in the context of SAP BW (Business Warehouse) when there is an issue with the aggregation process of InfoCubes or when the system encounters an unexpected error during the execution of a check for aggregates.
  Causes:
  
  Data Inconsistencies: There may be inconsistencies in the data that the aggregate is trying to process.
  Corrupted Aggregates: The aggregate itself may be corrupted or not properly defined.
  System Resource Issues: Insufficient memory or other system resources can lead to unexpected terminations.
  Transport Issues: If the aggregate was recently transported from another system, it may not have been properly configured.
  Database Issues: Problems with the underlying database, such as locks or corruption, can also lead to this error.
  
  Solutions:
  
  
  Check for Data Consistency:
  
  Use transaction codes like RSA1 to check the data in the InfoCube and ensure there are no inconsistencies.
  Run the RSD1 transaction to check the InfoObject definitions and ensure they are correct.
  
  
  
  Rebuild the Aggregate:
  
  If the aggregate is corrupted, you may need to delete and recreate it. This can be done in the RSA1 transaction under the Aggregates section.
  You can also use the RSD1 transaction to check the aggregate and see if it can be repaired.
  
  
  
  Monitor System Resources:
  
  Check the system logs and monitor memory usage to ensure that there are sufficient resources available.
  If necessary, increase the memory allocation for the SAP system.
  
  
  
  Check Transport Logs:
  
  If the issue arose after a transport, review the transport logs to ensure that all objects were transported correctly and that there were no errors during the transport process.
  
  
  
  Database Checks:
  
  Perform database checks to ensure that there are no locks or corruption issues. This may involve working with your database administrator to run consistency checks.
