  Solution:
  
  Check Data Types: Review the data types involved in the conversion. Ensure that they are compatible and that the conversion logic is appropriate for the types being used.
  Implement Conversion Logic: If you are working with custom data types or formats, you may need to implement a conversion routine. This can be done using ABAP code or by configuring the necessary conversion settings in the system.
