• What is the cause and solution for SAP error message EDX_WS009 - Non-permitted character found in Base64 string: &1 &2 ?

  The SAP error message EDX_WS009 indicates that there is a non-permitted character found in a Base64 string. This typically occurs when data that is expected to be in Base64 format contains characters that are not valid in that encoding scheme.
  Cause:
  
  Invalid Characters: Base64 encoding only allows a specific set of characters (A-Z, a-z, 0-9, +, /, and = for padding). Any other character will trigger this error.
  Data Corruption: The data being processed may have been corrupted or improperly formatted before being encoded.
  Improper Encoding: The data may not have been encoded correctly into Base64 format before being sent to the SAP system.
  Transmission Errors: If the Base64 string is being transmitted over a network, it may have been altered or corrupted during transmission.
  
  Solution:
  
  Validate Input Data: Check the source of the Base64 string to ensure that it is being generated correctly. Make sure that the data being encoded does not contain any invalid characters.
  Re-encode the Data: If you have access to the original data, try re-encoding it into Base64 using a reliable method or library.
  Check for Corruption: If the Base64 string is being received from an external source, verify that it has not been altered or corrupted during transmission.
  Debugging: Use debugging tools or logs to trace where the Base64 string is being generated and identify any potential issues in the encoding process.
  Error Handling: Implement error handling in your code to catch and manage such errors gracefully, providing meaningful feedback to users or systems.
  
  Related Information:
  
  Base64 Encoding: Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used in data transmission and storage.
  SAP Documentation: Refer to SAP's official documentation or support notes for more specific guidance related to the context in which this error occurs.
  Encoding Libraries: If you are working with programming languages, consider using built-in libraries or functions for Base64 encoding to avoid manual errors.
