• What is the cause and solution for SAP error message SDDL_PARSER_MSG293 - Child-to-parent association &1 is not allowed in extend views ?

  The SAP error message SDDL_PARSER_MSG293 indicates that there is an issue with the association between child and parent entities in an extended view definition. This error typically arises when you attempt to create a child-to-parent association in an extended view, which is not permitted in SAP's Core Data Services (CDS) views.
  Cause:
  The error occurs because:
  
  In SAP CDS views, child-to-parent associations are not allowed in extended views. Extended views are meant to add additional fields or logic to existing views, but they cannot redefine the relationships between entities.
  The association you are trying to create violates the rules of the CDS view definition.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the View Definition: Check the definition of your extended view. Ensure that you are not trying to create a child-to-parent association. Instead, you should only define associations that are valid in the context of an extended view.
  
  
  Use Existing Associations: If you need to reference a parent entity, use the existing associations defined in the base view. You can access parent attributes through the existing associations without redefining them.
  
  
  Modify the View Logic: If you need to change the relationship, consider creating a new base view or modifying the existing base view instead of extending it. This way, you can define the necessary associations correctly.
  
  
  Check Documentation: Refer to the SAP documentation for Core Data Services (CDS) to understand the rules and limitations regarding associations in extended views.
  
  
  Related Information:
  
  Core Data Services (CDS): A framework for defining and consuming semantically rich data models in SAP applications.
  Extended Views: These are views that build upon existing views to add additional fields or logic but do not change the underlying associations.
  Associations in CDS: Understand the difference between associations and how they can be used in base views versus extended views.
  
  By following these guidelines, you should be able to resolve the SDDL_PARSER_MSG293 error and correctly define your views in SAP.
