  The SAP error message /BOBF/CONF_CDS049 [BO check] Key type has to be 'legacy' like parent view (view &1) typically occurs in the context of Business Object Framework (BOF) and Core Data Services (CDS) views in SAP. This error indicates that there is a mismatch in the key type definition between a child view and its parent view.
  
  Cause:
  
  Key Type Mismatch: The error arises when the key type of a child view is not set to 'legacy', while the parent view (referenced in the error message) is defined with a key type of 'legacy'. In SAP, key types can be defined as 'legacy' or 'non-legacy', and they must be consistent across parent-child relationships in the data model.
  Modeling Error: This can happen due to incorrect modeling of the CDS views or Business Object definitions, where the child view is expected to inherit the key type from the parent view.
