• What is the cause and solution for SAP error message CAWUSL114 - Numerous rows can cause performance problems ?

  The SAP error message CAWUSL114 indicates that a query or operation is returning a large number of rows, which can lead to performance issues. This message is typically seen in the context of SAP BW (Business Warehouse) or SAP HANA, where large datasets can impact the performance of reports, queries, or data processing tasks.
  Cause:
  
  Large Dataset: The query or operation is attempting to retrieve or process a large number of records, which can overwhelm the system's resources.
  Inefficient Query Design: The query may not be optimized, leading to unnecessary data retrieval.
  Lack of Filters: The absence of filters or selection criteria can result in fetching more data than needed.
  Data Model Issues: Poorly designed data models or inflexible data structures can contribute to excessive data retrieval.
  
  Solution:
  
  
  Optimize Queries:
  
  Review and optimize the query design to ensure it only retrieves necessary data.
  Use appropriate filters to limit the number of rows returned.
  Consider aggregating data where possible to reduce the volume of rows.
  
  
  
  Use Variables:
  
  Implement variables in your queries to allow users to specify criteria, thus reducing the number of rows returned.
  
  
  
  Adjust Data Model:
  
  Reassess the data model to ensure it is designed for efficient querying. This may involve creating summary tables or using star schema designs.
  
  
  
  Performance Tuning:
  
  Analyze the performance of the underlying database and consider indexing or partitioning strategies to improve query performance.
  
  
  
  Batch Processing:
  
  If applicable, consider processing data in smaller batches rather than attempting to handle large datasets all at once.
  
  
  
  Monitoring and Analysis:
  
  Use SAP's performance monitoring tools to analyze query performance and identify bottlenecks.
