• What is the cause and solution for SAP error message SDDIC_CSN019 - Query not exported. Entity &1 has composition association. ?

This typically occurs in the context of SAP Data Services or SAP HANA when trying to export a query that involves complex relationships between entities.

  Modify the Query:
  
  If possible, modify the query to avoid using composition associations. You might need to flatten the data structure or break down the query into simpler components that do not involve complex relationships.
  
  
  
  Use Alternative Export Methods:
  
  If the query cannot be simplified, consider using alternative methods for exporting the data. This could involve exporting the data in multiple steps or using different tools that can handle complex associations better.
  
  
  
  Check for Updates or Patches:
