• What is the cause and solution for SAP error message /SCMB/DM_DLV191 - ASN &1, item &2: Serial number &3 exists already ?

  The SAP error message /SCMB/DM_DLV191 indicates that there is an issue with the Advanced Shipping Notification (ASN) process in the Supply Chain Management (SCM) module. Specifically, the error message states that a serial number already exists for the specified item in the ASN. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  
  Duplicate Serial Number: The error occurs when an ASN is trying to include a serial number that has already been assigned to another delivery or shipment. This can happen if:
  
  The same serial number is being used for multiple items in the ASN.
  The serial number was previously processed and is still in the system.
  There is a data entry error where the same serial number is mistakenly entered for different items.
  
  
  
  Configuration Issues: There may be configuration settings in the system that enforce unique serial number assignments, leading to this error when duplicates are detected.
  
  
  Solution:
  
  
  Check Serial Number Assignment:
  
  Verify the serial number in question (&3) to see if it is already assigned to another delivery or shipment. You can do this by checking the serial number in the relevant transaction (e.g., using transaction code IQ03 to display serial numbers).
  If the serial number is indeed already assigned, you will need to use a different serial number for the ASN.
  
  
  
  Review ASN Data:
  
  Check the ASN data for duplicates. Ensure that each item in the ASN has a unique serial number.
  If duplicates are found, correct the ASN by removing or changing the serial numbers as necessary.
  
  
  
  Adjust Configuration:
  
  If the issue is related to configuration settings, consult with your SAP Basis or SCM configuration team to review the settings related to serial number management. Ensure that the system is set up correctly to handle serial numbers as per your business requirements.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to serial number management and ASN processing for additional guidance and best practices.
  
  
  
  Related Information:
  
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  IQ01 (Create Serial Number)
  IQ02 (Change Serial Number)
  IQ03 (Display Serial Number)
  VL31N (Create ASN)
  
  
  
  SAP Notes: Check for any SAP Notes that may address this specific error or provide additional troubleshooting steps.
  
  
  User Roles and Authorizations: Ensure that the user processing the ASN has the necessary authorizations to view and modify serial numbers.
  
  
  By following these steps, you should be able to resolve the error and successfully process the ASN. If the problem persists, consider reaching out to SAP support for further assistance.
