This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA environments, where database performance and optimization are crucial for efficient data retrieval and processing.
  Cause:
  The error arises when the database statistics for a particular table are outdated or missing. Database statistics are essential for the query optimizer to make informed decisions about how to execute queries efficiently. If a table has not been analyzed, the optimizer may not have the necessary information to choose the best execution plan, which can lead to performance issues.
  Solution:
  To resolve this error, you need to analyze the affected table. The steps to do this may vary depending on the database system you are using (e.g., SAP HANA, Oracle, etc.), but generally, the process involves the following:
  
  
  Identify the Table: Determine which table is referenced in the error message (the name will replace &1).
  
  
  Analyze the Table:
  
  For SAP HANA:
  
  You can use the SQL command:
  ANALYZE TABLE <schema_name>.<table_name>;
  
  
  
  For Oracle:
  
  You can use the DBMS_STATS package:
  EXEC DBMS_STATS.GATHER_TABLE_STATS('<schema_name>', '<table_name>');
  
  
  
  For MaxDB:
  
  Use the command:
  ANALYZE TABLE <table_name>;
  
  
  
  
  
  
  Schedule Regular Analysis: To prevent this issue from recurring, consider scheduling regular analysis of your database tables. This can often be done through database maintenance jobs or SAP BW process chains.
  
  
  Check for Other Issues: If the problem persists after analyzing the table, check for other underlying issues such as database connectivity, permissions, or configuration settings.
  
  
  Related Information:
