This error typically occurs when using the SAP Gateway or when working with OData services in the context of SAP's ABAP programming model, particularly when dealing with data access layers (SADL).
  Cause:
  The error is caused by one of the following scenarios:
  
  Empty Filter Value: A filter condition is defined in your OData query, but the value for that filter is not provided (i.e., it is empty).
  Incorrect Data Type: The filter is expecting a specific data type (String, Integer, Decimal), but the provided value does not match the expected type or is missing.
  Configuration Issues: There may be issues in the configuration of the OData service or the underlying data model that lead to this error.
  
  Solution:

  Check the OData Query: Review the OData query being sent to ensure that all required filter values are provided. Make sure that the filter parameters are not empty.
  
  
  Validate Data Types: Ensure that the values being passed in the filter match the expected data types. For example, if the property expects an integer, make sure you are not passing a string or leaving it empty.
  
  
  Debugging: If you have access to the backend, you can debug the OData service to see what values are being processed and where the empty value is coming from.
  
  
  Review Service Configuration: Check the configuration of the OData service in the SAP Gateway. Ensure that the service is correctly set up to handle the filters you are trying to apply.
  
  
  Error Handling: Implement error handling in your application to catch such issues and provide meaningful feedback to the user.
  
  
  Documentation: Refer to the SAP documentation for the specific OData service you are using to understand the expected parameters and their data types.
