• What is the cause and solution for SAP error message /SCWM/SERIAL105 - Unique item identifier &1 already exists ?

  The SAP error message /SCWM/SERIAL105 Unique item identifier &1 already exists typically occurs in the context of the SAP Extended Warehouse Management (EWM) module when you are trying to create or manage a serial number that is already in use. This error indicates that the system has detected a duplicate entry for a unique item identifier (serial number) that you are attempting to use.
  Cause:
  
  Duplicate Serial Number: The most common cause of this error is that the serial number you are trying to enter already exists in the system for the same material or product.
  Incorrect Data Entry: There may have been a mistake in data entry, leading to the attempt to create a serial number that is already registered.
  System Configuration: The system may be configured to enforce unique serial numbers across certain materials or product categories, leading to this error when duplicates are detected.
  
  Solution:
  
  Check Existing Serial Numbers: Verify if the serial number you are trying to use already exists in the system. You can do this by searching for the serial number in the relevant transaction or report.
  Use a Different Serial Number: If the serial number is indeed already in use, you will need to use a different, unique serial number for your transaction.
  Review Serial Number Management Settings: If you believe the serial number should not be unique (for example, if it is a shared serial number across different materials), review the configuration settings in SAP EWM to ensure they align with your business processes.
  Consult with IT or SAP Support: If you are unable to resolve the issue, it may be beneficial to consult with your IT department or SAP support team for further assistance. They can help investigate the issue in more detail and provide guidance based on your specific system configuration.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like /SCWM/PRDI (Product Data) or /SCWM/PRD1 (Product Master) to check existing serial numbers.
  Documentation: Refer to SAP Help documentation for Extended Warehouse Management for more details on serial number management and error handling.
  User Exits and BAdIs: If your organization has custom logic implemented, check for any user exits or BAdIs that might affect serial number handling.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
