• What is the cause and solution for SAP error message WE235 - Check digit cannot be determined for EAN & since EAN alphanumeric ?

  SAP Error Message:
  WE235 - Check digit cannot be determined for EAN & since EAN alphanumeric
  
  
  Cause:
  The error WE235 occurs during IDoc processing (typically inbound or outbound) when the system tries to calculate or validate the check digit of an EAN (European Article Number) but fails because the EAN contains alphanumeric characters instead of only numeric digits.

If the EAN contains letters or other non-numeric characters, the standard check digit calculation logic cannot be applied, resulting in this error.
  
  Explanation:
