• What is the cause and solution for SAP error message WE240 - EAN with determined check digit: & ?

  SAP Error Message:
  
  WE240 – "EAN with determined check digit: &"
  
  Meaning / Cause:
  The error message WE240 occurs during IDoc processing or EDI message handling when the system detects an EAN (European Article Number) or GTIN (Global Trade Item Number) with an incorrect or invalid check digit.
  
  The EAN/GTIN is a barcode number used to uniquely identify products.
  The last digit of the EAN is a check digit, calculated from the preceding digits using a specific algorithm (modulus 10).
  If the check digit does not match the calculated value, SAP raises this error.
  The placeholder "&" in the message is replaced by the incorrect check digit found or the problematic EAN number.
  
  
  Technical Background:
  
  The check digit is calculated using the standard EAN/GTIN algorithm:
  
  Sum all digits in odd positions (from right to left).
  Sum all digits in even positions and multiply by 3.
  Add the two sums.
  The check digit is the number that must be added to this total to reach the next multiple of 10.
  
  
  If the provided check digit does not match this calculation, the EAN is considered invalid.
  
  
  When does this error occur?
  
  During inbound IDoc processing (e.g., ORDERS, INVOIC, DESADV) when the system validates EANs.
  During outbound message generation if the system tries to validate or generate EANs.
  When EANs are maintained or validated in material master or related master data.
  During EDI inbound processing if the EAN number in the message is incorrect.
  
  
  Solution / How to fix:
  
  
  Check the EAN number:
  
  Verify the EAN number in the source data (e.g., IDoc segment, EDI message, material master).
  Confirm that the EAN number is correct and complete (usually 8, 12, 13, or 14 digits).
  
  
  
  Recalculate the check digit:
  
  Use an EAN check digit calculator (many online tools available) to verify the correct check digit.
  Correct the EAN number in the source system or master data if the check digit is wrong.
  
  
  
  Correct the data in SAP:
  
  If the EAN is stored in material master (transaction MM02), update the EAN/GTIN with the correct number.
  If the EAN comes from an external system or EDI partner, request corrected data.
  
  
  
  Check IDoc or EDI message:
  
  If the error occurs during IDoc inbound processing, check the inbound IDoc segments (e.g., E1EDP01 for item data).
  Correct the EAN in the sending system or map the correct EAN in the interface.
  
  
  
  Disable check digit validation (not recommended):
  
  In some cases, if validation is not required, you can disable check digit validation in the system.
  This is generally not recommended as it may lead to data inconsistencies.

  Summary:
  
  Cause: Invalid EAN number with incorrect check digit.
  Solution: Verify and correct the EAN number/check digit in the source data or master data.
  Check: Use standard EAN check digit calculation to validate.
  Avoid: Disabling validation unless absolutely necessary.
