  The SAP error message DDLS295 indicates that there is a missing definition for an association in the Data Dictionary. This typically occurs when you are trying to activate or generate a data model (like a CDS view or a table) that references an association that has not been properly defined or is missing.
  Cause:
  
  Missing Association Definition: The association you are trying to use in your data model is not defined in the relevant context (e.g., in the CDS view or the underlying table).
  Incorrect Naming: There might be a typo or incorrect naming in the association definition.
  Transport Issues: If the association was recently created or modified, it might not have been transported correctly to the system where you are encountering the error.

  Solution:
  
  Check Association Definition: Verify that the association is defined correctly in the relevant CDS view or data model. Ensure that the source and target entities are correctly specified.
