This can occur in various scenarios, such as when data is being transferred between different structures or when there are inconsistencies in the data types or formats.
  Cause

  Data Type Mismatch: The source and target fields may have incompatible data types, leading to conversion failures.
  Invalid Data: The data being processed may not conform to the expected format or range, causing the conversion rule to fail.
  Configuration Issues: There may be issues in the BOPF configuration, such as incorrect mapping definitions or missing conversion rules.
  Custom Logic: If there is custom logic implemented in the conversion rules, it may contain errors or may not handle certain cases properly.

  Review Mapping Configuration: Go to the BOPF configuration and review the mapping definitions for the relevant business object. Ensure that all necessary conversion rules are defined and correctly implemented.
  
  
  Debug Custom Logic: If there is custom logic involved in the conversion, debug the code to identify any issues. Look for any assumptions made in the code that may not hold true for all data inputs.
