  The SAP error message SD_CDS_ENTITY045 indicates that a specific field (denoted as &1) is still being used in an association (denoted as &3) of a particular entity (denoted as &2). This typically occurs in the context of Core Data Services (CDS) views in SAP, where certain fields are expected to be removed or modified, but they are still referenced in the associations of the CDS entity.
  Cause
  The error is usually caused by one of the following reasons:
  
  Field Removal: You may have attempted to remove a field from a CDS entity that is still being referenced in one of its associations.
  Association Definition: The association might be defined in such a way that it still relies on the field that you are trying to modify or delete.
  Model Changes: Changes in the underlying data model or structure that have not been fully propagated through the associated entities.
  
  Solution
  To resolve this error, you can follow these steps:
  
  
  Check Associations: Review the associations defined in the CDS entity. Identify where the field &1 is being used and determine if it is necessary for the association.
  
  
  Modify or Remove References: If the field is no longer needed, you will need to modify the association to remove the reference to the field. This may involve changing the join conditions or the fields being selected in the association.
  
  
  Update the CDS View: After making the necessary changes to the associations, update the CDS view definition to ensure that it reflects the current data model.
  
  
  Activate the CDS View: Once the changes are made, activate the CDS view to ensure that the changes take effect.
  
  
  Test the Changes: After activation, test the CDS view to ensure that it behaves as expected and that the error message no longer appears.
