  The SAP error message /UI2/TINY_DATA004 Base conversion failed typically occurs in the context of SAP Fiori applications or when dealing with OData services. This error indicates that there was an issue converting data types, often related to the handling of numeric or string values in the backend or frontend.
  Causes:
  
  Data Type Mismatch: The error can occur if there is a mismatch between the expected data type in the OData service and the actual data being processed. For example, if a numeric value is expected but a string is provided.
  Invalid Data Format: If the data being sent to the OData service does not conform to the expected format (e.g., incorrect decimal separators, invalid characters), it can lead to conversion failures.
  Null or Empty Values: Attempting to convert null or empty values can also trigger this error, especially if the conversion logic does not handle such cases properly.

  Solutions:
  
  Check Data Types: Review the data types defined in the OData service and ensure that the data being sent matches these types. This includes checking for numeric, string, and date formats.
  Validate Input Data: Implement validation checks on the input data to ensure that it conforms to the expected formats before sending it to the OData service.
  Handle Null Values: Modify the backend logic to handle null or empty values appropriately, ensuring that they do not cause conversion errors.
  Debugging: Use debugging tools in SAP (such as transaction SE80 or SE37) to trace the execution of the OData service and identify where the conversion is failing.
  Check Fiori Configuration: If the error occurs in a Fiori application, check the configuration settings and ensure that the application is correctly set up to handle the data being processed.
