• What is the cause and solution for SAP error message WE065 - Check-digit algorithm for EAN allows numeric entries only ?

  Certainly! Here's a detailed explanation regarding the SAP error message WE065: "Check-digit algorithm for EAN allows numeric entries only":
  
  Error Message:
  WE065 - Check-digit algorithm for EAN allows numeric entries only
  
  Cause:
  This error occurs during the processing of EAN (European Article Number) codes in IDocs or master data when the system tries to validate the check digit of an EAN code that contains non-numeric characters.
  
  The EAN check-digit algorithm expects the EAN code to be numeric only (digits 0-9).
  If the EAN code contains alphabetic characters or special characters, the check-digit validation fails and triggers this error.
  This often happens when the EAN code field is populated incorrectly, or the data source contains invalid characters.
  
  
  Where it occurs:
  
  During IDoc inbound or outbound processing involving material master or vendor/customer master data.
  When validating EAN/GTIN codes in material master data.
  In ALE/EDI scenarios where EAN codes are exchanged.
  
  
  Solution:
  
  
  Check the EAN code data:
  
  Verify that the EAN code contains only numeric digits.
  Remove any alphabetic or special characters from the EAN code.
  Ensure the length of the EAN code is correct (usually 8, 12, 13, or 14 digits depending on the EAN/GTIN standard).
  
  
  
  Correct the source data:
  
  If the EAN code is coming from an external system or file, correct the data at the source.
  If the data is manually entered, ensure users enter only numeric digits.
  
  
  
  Data cleansing:
  
  Run a data cleansing program or report to identify and fix invalid EAN codes in the system.
  
  
  
  Check configuration:
  
  In some cases, the check-digit algorithm might be customized or configured incorrectly.
  Verify the check-digit algorithm settings in transaction WE20 or related IDoc processing configurations.
  
  
  
  If non-numeric characters are required (rare case):
  
  The standard EAN check-digit algorithm does not support non-numeric characters.
  You may need to bypass the check-digit validation or customize the validation logic (not recommended as it breaks standards).
  
  
  
  
  Additional Information:
  
  EAN/GTIN codes are standardized product identifiers used globally.
  The check-digit is a form of error detection to ensure the code is valid.
  SAP uses standard algorithms to validate these codes during master data maintenance and IDoc processing.
  The error message is part of the standard SAP message class WE (EDI/IDoc processing).

  WE065 - Check-digit algorithm for EAN allows numeric entries only
  
  
  Cause
  EAN code contains non-numeric characters, violating the numeric-only check-digit rule
  
  
  Solution
  Ensure EAN codes contain only digits; correct source data; cleanse existing data
