  The SAP error message /IWBEP/CM_V4_RUNTIME005 typically occurs in the context of OData services when there is an issue with the filter expression being used in a query. This specific error indicates that the filter contains a function that has a parameter requiring conversion, which means that the data type of the parameter does not match the expected type for the function being called.
  Cause:
  
  Data Type Mismatch: The parameter being passed to a function in the filter expression does not match the expected data type. For example, if a function expects a string but receives an integer, this error may occur.
  Unsupported Functions: The function used in the filter may not be supported by the OData service or may not be properly defined in the service metadata.

  Review Function Usage: Verify that the function being used in the filter is supported by the OData service and that it is being used correctly according to the service documentation.
  Modify the Filter Expression: If the filter expression is incorrect, modify it to ensure that it adheres to the expected syntax and data types. For example, if you are using a function like substring, ensure that the parameters are of the correct type.
  Test with Simple Queries: Start with a simpler filter expression to isolate the issue. Gradually add complexity to identify the specific part of the filter that is causing the error.
  Check Service Metadata: Review the OData service metadata to understand the expected data types and functions available for use in filters.
