  The SAP error message /IWBEP/CM_CP223 with the description "CP expression '&1' in range table not allowed" typically occurs in the context of SAP Gateway or OData services when there is an issue with the way a filter expression is defined in a query.
  Cause:
  This error is generally caused by the following reasons:
  
  
  Invalid Filter Expression: The filter expression used in the OData query is not valid or is not supported. This can happen if you are trying to use a complex expression that is not allowed in the context of the range table.
  
  
  Unsupported Operators: Certain operators or functions may not be supported in the context of the OData service or the underlying data model.
  
  
  Data Type Mismatch: The data type of the field being filtered may not match the expected type, leading to an invalid expression.
  
  
  Range Table Limitations: The range table used in the query may have limitations on the types of expressions that can be used.
  
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Review the Filter Expression: Check the filter expression you are using in your OData query. Ensure that it adheres to the syntax and semantics expected by the OData service.

  Check Data Types: Ensure that the data types of the fields you are filtering on match the expected types. For example, if you are filtering on a numeric field, ensure that you are not passing a string.
  
  
  Consult Documentation: Refer to the SAP Gateway documentation or the specific OData service documentation to understand the supported filter expressions and operators.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see how the filter is being processed and identify where the issue lies.
  
  
  Test with Different Values: Sometimes, specific values may cause issues. Test the query with different filter values to see if the error persists.
