  Cause:
  The error can be caused by several factors, including:
  
  
  Data Type Mismatch: The value in the field may not be compatible with the expected data type. For example, if a numeric field is expected but a string is provided, the conversion will fail.
  
  
  Missing Master Data: If the internal value corresponds to a key in a master data table that does not exist, the system will not be able to convert it to an external format.
  
  
  Incorrect Data Format: The internal representation of the data may not match the expected format for conversion. This can happen if the data was loaded incorrectly or if there are inconsistencies in the data.
  
  
  Custom Code or Enhancements: If there are custom ABAP programs or enhancements that manipulate the data, they may introduce errors that lead to this conversion issue.

  Debugging: If you have access to the ABAP debugger, you can set breakpoints in the relevant code to see where the conversion is failing. This can help identify the specific value causing the issue.
  
  
  Data Load Process: Review the data load process to ensure that data is being loaded correctly. Check for any errors or warnings during the data load that might indicate issues.
