  The SAP error message /IWBEP/CM_V4_MED057 Parameter '&1' is EDM-based typically occurs in the context of OData services when there is an issue with the way parameters are defined or used in the service. This error indicates that a parameter being referenced is based on the Entity Data Model (EDM), but it is not being handled correctly in the request or the service implementation.
  Cause:
  
  EDM-based Parameter: The parameter in question is defined in the EDM, which means it is expected to follow certain conventions and data types as defined in the OData service metadata.
  Incorrect Parameter Usage: The parameter might be used incorrectly in the OData request, such as using the wrong data type, missing required parameters, or providing parameters that are not defined in the EDM.
  Service Implementation Issues: There may be issues in the implementation of the OData service that do not correctly handle the EDM-based parameters.
  
  Solution:
  
  Check Parameter Definition: Review the OData service metadata (usually accessible via the $metadata endpoint) to ensure that the parameter is correctly defined and that you are using the correct name and data type in your request.
  Validate Request Format: Ensure that the OData request is correctly formatted. Check for:
  
  Correct parameter names.
  Proper data types (e.g., string, integer).
  Required parameters are included in the request.
  
  
  Review Service Implementation: If you have access to the service implementation, check the logic that processes the parameters. Ensure that it correctly handles EDM-based parameters.
  Debugging: If possible, enable debugging or logging for the OData service to capture more detailed error messages or stack traces that can help identify the root cause.
  Consult Documentation: Refer to SAP documentation or community forums for any specific notes or updates related to the OData service you are using.
  
  Related Information:
  
  OData Protocol: Understanding the OData protocol and how it interacts with SAP systems can provide insights into how parameters are defined and used.
