  The SAP error message CFD_REPOSITORY_HNDLR037 indicates that a specific field (denoted as &1) cannot be deleted because it is still referenced in another field (denoted as &2). This is a common issue when working with data models, especially in the context of SAP's Core Data Services (CDS) or other data repository configurations.
  Cause:
  
  
  Field Dependency: The field you are trying to delete is being used in another field, view, or data structure. This could be due to:
  
  The field being part of a calculation or aggregation.
  The field being referenced in a join or relationship.
  The field being used in a validation or business logic.
  
  
  
  Data Model Integrity: SAP enforces data integrity rules to ensure that all references are valid. Attempting to delete a field that is still in use violates these rules.

  Identify References:
  
  Check where the field (&1) is being used. You can do this by:

  Checking any associated views, tables, or structures that might reference the field.

  Editing the data model to remove the dependency.
  Modifying any calculations, joins, or validations that use the field.
  
  
  
  
  
  Delete the Field:
