• What is the cause and solution for SAP error message /SCMB/DM_DLV255 - ASN &1, item &2: Serial number is longer than 18 characters ?

  The SAP error message /SCMB/DM_DLV255 ASN &1, item &2: Serial number is longer than 18 characters indicates that there is an issue with the serial number associated with an Advanced Shipping Notification (ASN) in the Supply Chain Management (SCM) module. Specifically, the error arises when the serial number exceeds the maximum allowed length of 18 characters.
  Cause:
  
  
  Serial Number Length: The primary cause of this error is that the serial number being processed is longer than the allowed limit of 18 characters. This can happen due to incorrect data entry, system integration issues, or data migration problems where serial numbers were not properly validated.
  
  
  Data Source: The serial number may be coming from an external system or a manual entry that does not adhere to the length restrictions set in SAP.
  
  
  Solution:
  
  
  Check Serial Number: Review the serial number associated with the ASN and ensure it does not exceed 18 characters. If it does, you will need to truncate or modify the serial number to fit within the limit.
  
  
  Data Validation: Implement data validation checks in the system or during data entry to prevent serial numbers longer than 18 characters from being entered in the future.
  
  
  Update Integration Logic: If the serial numbers are being imported from an external system, check the integration logic to ensure that it enforces the character limit before sending data to SAP.
  
  
  Correct Data Entry: If the serial number was entered manually, correct the entry to ensure compliance with the character limit.
  
  
  Consult Documentation: Review SAP documentation or configuration settings related to serial number management to ensure that the system is set up correctly.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling serial numbers in the SCM module.
  Transaction Codes: Familiarize yourself with transaction codes related to ASN processing and serial number management, such as /SCMB/ASN or MM02 for material master changes.
  User Training: Ensure that users involved in data entry or ASN processing are trained on the importance of adhering to character limits for serial numbers.
  
  By addressing the root cause of the error and implementing preventive measures, you can resolve the issue and avoid similar errors in the future.
