• What is the cause and solution for SAP error message SADL_ENTITY_CDS010 - Composition hierarchy of the CDS entity &1 is inconsistent ?

  The SAP error message SADL_ENTITY_CDS010 indicates that there is an inconsistency in the composition hierarchy of a Core Data Services (CDS) entity. This typically occurs when there are issues with the relationships defined in the CDS views, particularly when dealing with associations or compositions.
  Cause
  The inconsistency can arise from several factors, including:
  
  Incorrect Associations: The associations defined in the CDS view may not be correctly set up, leading to a mismatch in the expected hierarchy.
  Missing Annotations: Required annotations for the CDS entity may be missing, which can lead to issues in how the data is structured or accessed.
  Changes in Underlying Data Model: If there have been changes in the underlying data model (like changes in tables or fields), the CDS view may not reflect these changes correctly.
  Circular References: There may be circular references in the composition hierarchy, which can cause inconsistencies.
  Inconsistent Data: The data in the underlying tables may not conform to the expected structure, leading to inconsistencies when the CDS view is accessed.
  
  Solution
  To resolve the SADL_ENTITY_CDS010 error, you can take the following steps:
  
  
  Check Associations: Review the associations defined in the CDS view. Ensure that they are correctly defined and that the target entities exist and are accessible.
  
  
  Validate Annotations: Ensure that all required annotations are present in the CDS view. This includes checking for annotations related to composition and association.
  
  
  Review Data Model Changes: If there have been recent changes to the underlying data model, ensure that the CDS view has been updated accordingly. You may need to regenerate the CDS view or adjust it to align with the new data model.
  
  
  Check for Circular References: Look for any circular references in the composition hierarchy and resolve them by restructuring the associations.
  
  
  Data Consistency Check: Perform a consistency check on the underlying data to ensure that it adheres to the expected structure. This may involve checking for null values, data types, and referential integrity.
  
  
  Rebuild the CDS View: If the issue persists, consider rebuilding the CDS view from scratch to ensure that all elements are correctly defined.
  
  
  Consult Documentation: Refer to SAP documentation for any specific guidelines or best practices related to the CDS views and their composition hierarchies.
