  Type Conversion: If necessary, perform explicit type conversion in your code to ensure that the values being assigned are of the correct type. For example, if you need to convert a string to an integer, use appropriate conversion functions.
  Consult Documentation: Refer to the SAP documentation for the specific BSP components you are using to understand the expected types and any constraints that may apply.
