  Cause
  
  
  Invalid Input: The input string that is being processed is not a valid Base64 encoded string. This could be due to:
  
  Corruption of the data.
  Incorrect formatting or characters that are not part of the Base64 character set (A-Z, a-z, 0-9, +, /, and = for padding).
  
  
  
  Encoding Issues: The data might have been encoded using a different method or has been altered in transit, leading to an invalid Base64 string.
  
  
  Truncated Data: The data might be incomplete or truncated, which can happen if the data was not fully transmitted or saved.
  
  
  Solution
  
  
  Validate Input: Check the input string to ensure it is a valid Base64 encoded string. You can use online Base64 validators or libraries in programming languages to verify the encoding.
  
  
  Re-encode Data: If you have access to the original data, try re-encoding it to Base64 and then attempt the decoding process again.
  
  
  Check Data Source: Investigate the source of the data to ensure that it is being generated and transmitted correctly. Look for any issues in the data pipeline that might be causing corruption.
  
  
  Error Handling: Implement error handling in your code to gracefully manage cases where the input is not valid Base64. This can include logging the error and providing feedback to the user.
  
  
  SAP Notes: Check SAP Notes and documentation for any known issues or patches related to this error message. Sometimes, specific versions of SAP may have bugs that are addressed in later updates.
