automatically. However, the corresponding field already contains an EAN
with EAN category &V1&.

System Response

The system cannot tell whether the EAN has been entered manually or
already assigned internally. When you select <LS>Enter</>, the system

  SAP Error Message: WE233
  Text:
  
  EAN cat.&: check digit will be created for EAN & poss.assigned internally
  
  1. Cause of the Error
  
  The message WE233 is an information or warning message (not an error that stops processing) that appears during IDoc processing, specifically when handling EAN (European Article Number) or GTIN (Global Trade Item Number) fields.
  It indicates that the system has detected an EAN number without a valid check digit or with an incorrect check digit.
  SAP automatically calculates and assigns the correct check digit internally for the EAN number.
  The message is triggered because the EAN number received in the IDoc segment is incomplete or the check digit is missing/incorrect, so SAP corrects it to ensure data integrity.
  
  
  2. Explanation
  
  EAN (European Article Number) or GTIN is a barcode standard that includes a check digit for validation.
  The check digit is calculated using a specific algorithm (modulus 10) to ensure the number is valid.
  If the incoming EAN number lacks this check digit or has an incorrect one, SAP will generate the correct check digit automatically.
  The message informs the user or developer that this automatic correction has taken place.
  
  
  3. Solution / How to Handle
  
  No immediate action is required if the message appears as an informational message and the EAN number is corrected automatically.
  However, to avoid this message and ensure data quality:
  
  Check the source system or data provider to ensure that EAN numbers sent in IDocs or master data include the correct check digit.
  Validate EAN numbers before sending to SAP to prevent automatic correction.
  If you want to suppress this message (if it appears as a warning and clutters logs), you can adjust message control or partner profile settings, but this is generally not recommended as it hides potentially useful information.
  
  
  If the message appears as an error and stops processing (rare), then you need to:
  
  Correct the EAN number in the source data.
  Reprocess the IDoc after correction.
  
  
  
  
  4. Related Information
  
  IDoc Segment: This message typically appears during processing of IDocs related to material master data (e.g., MATMAS), purchase orders (ORDERS), or other documents containing EAN/GTIN fields.
  Check Digit Calculation: SAP uses the standard EAN/GTIN check digit algorithm (modulus 10) to calculate the check digit.
  Transaction Codes:  
  
  Use WE02 or WE05 to view IDocs and check for this message in the status records.
  Use BD87 to reprocess IDocs after correction.
  
  
  SAP Notes:

  Customization:  
  
  In some cases, the EAN check digit validation can be influenced by customizing in Logistics ? General ? Basic Settings ? Check Digit for EAN.
