  The SAP error message CL_RAP_OPXY_EDMX_MSG027 typically indicates that there is a mismatch in the expected entity set type in the context of the RAP (Rapid Application Programming) model. This error occurs when the entity set being referenced has a different type than what is expected in the operation being performed.
  Cause:
  
  Type Mismatch: The entity set you are trying to access or manipulate has a different type than what is defined in the RAP model. This could be due to incorrect configuration or a misunderstanding of the entity types.
  Model Definition Issues: There may be issues in the definition of the entity sets in the CDS (Core Data Services) views or in the RAP business object definitions.
  Inconsistent Metadata: The metadata for the entity set may not be consistent with the actual data model, leading to discrepancies.
  
  Solution:
  
  Check Entity Set Definitions: Review the definitions of the entity sets in your CDS views or RAP business object definitions. Ensure that the types are correctly defined and consistent with what is expected.
  Validate Metadata: Use transaction codes like SE11 or SE80 to check the metadata of the entity sets and ensure that they match the expected types.
  Adjust the Operation: If you are performing an operation that expects a specific type, ensure that you are passing the correct entity set type. This may involve modifying the operation or the data being passed to it.
  Rebuild the Model: If changes have been made to the underlying data model, consider regenerating or rebuilding the RAP model to ensure that all definitions are up to date.
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as there may be bug fixes related to RAP and entity set handling.
