• What is the cause and solution for SAP error message /IWBEP/CM_CP050 - Invalid V2 EDM conversion: Function parameter type '&1' ?

  The SAP error message /IWBEP/CM_CP050 Invalid V2 EDM conversion: Function parameter type '&1' typically occurs in the context of SAP Gateway and OData services. This error indicates that there is an issue with the conversion of a function parameter type in the OData service, specifically when the system is trying to map the parameter type to an Entity Data Model (EDM) type.
  Causes:
  
  Unsupported Data Type: The function parameter type being used is not supported for conversion to the EDM type. This can happen if the parameter type is a complex type or a type that is not recognized by the OData service.
  Incorrect Mapping: There may be an issue with how the parameter is defined in the service or how it is being mapped to the corresponding EDM type.
  Version Mismatch: If there are discrepancies between the versions of the OData service and the underlying data model, it can lead to conversion issues.
  Configuration Issues: There may be configuration issues in the OData service or the underlying function module that are causing the parameter type to be invalid.
  
  Solutions:
  
  Check Parameter Types: Review the function module or method that is being called and ensure that all parameter types are supported by the OData service. Common supported types include basic types like String, Int, Decimal, etc.
  Update OData Service: If the function module has been changed (e.g., new parameters added or types changed), regenerate the OData service to ensure that the changes are reflected in the service definition.
  Review EDM Mapping: Check the mapping of the function parameters to the EDM types in the service definition. Ensure that the mappings are correct and that all types are supported.
  Debugging: Use transaction /IWFND/ERROR_LOG to check for additional error messages or logs that may provide more context about the issue.
  Consult Documentation: Refer to SAP documentation for the specific version of the OData service you are using to ensure that you are following the correct guidelines for parameter types and mappings.
