• What is the cause and solution for SAP error message DD_CDS_ANALYSIS805 - The name of the association &1 is not unique in this context. ?

  The SAP error message DD_CDS_ANALYSIS805 indicates that there is a problem with the uniqueness of an association name in a Core Data Services (CDS) view. This error typically arises when you have defined multiple associations with the same name within the same context, which is not allowed in CDS views.
  Cause:
  The error occurs due to one of the following reasons:
  
  Duplicate Association Names: You have defined two or more associations with the same name in the same CDS view or in the context of the same entity.
  Inheritance Issues: If you are using inheritance in your CDS views, the same association name might be inherited from a parent view, leading to a conflict.
  Contextual Ambiguity: The context in which the association is being referenced is ambiguous due to multiple definitions.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Association Names: Review the CDS view definition and ensure that all association names are unique within the same context. Rename any duplicate associations to ensure uniqueness.
  
  
  Review Inheritance: If you are using inheritance, check the parent views for any associations that might be causing the conflict. You may need to rename the association in the child view or the parent view.
  
  
  Refactor the CDS View: If the associations are logically similar but need to be differentiated, consider refactoring your CDS view to separate the associations into different views or contexts.
  
  
  Use Aliases: If you need to reference the same association in different contexts, consider using aliases to differentiate them.
  
  
  Check for Typos: Sometimes, a simple typo can lead to unintended duplicate names. Ensure that all association names are spelled correctly and consistently.
