• What is the cause and solution for SAP error message SDDL_PARSER_MSG519 - Redefinitions of a locally defined association are not supported ?

  The SAP error message SDDL_PARSER_MSG519 indicates that there is an issue with the definition of associations in your data model, specifically that you are trying to redefine a locally defined association, which is not supported in the context of the SAP Data Definition Language (SDDL).
  Cause:
  This error typically arises when:
  
  You have defined an association in your data model (e.g., in an ABAP CDS view or a similar construct) and then attempted to redefine that association within the same scope or context.
  The association is being defined multiple times with different characteristics or properties, which is not allowed.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Association Definitions: Review your data model to identify where the association is defined. Ensure that you are not redefining it elsewhere in the same context.
  
  
  Use Unique Names: If you need to create a different association, ensure that it has a unique name. Avoid using the same name for different associations within the same entity or context.
  
  
  Refactor Your Model: If you need to change the properties of an existing association, consider refactoring your model to either:
  
  Modify the existing association instead of redefining it.
  Create a new entity or view that encapsulates the desired changes without conflicting with existing definitions.
  
  
  
  Consult Documentation: Refer to the SAP documentation for guidelines on defining associations in your specific context (e.g., ABAP CDS, OData services). This can provide insights into best practices and restrictions.
  
  
  Testing: After making changes, test your data model to ensure that the error is resolved and that the associations behave as expected.
