• What is the cause and solution for SAP error message /SCWM/SERIAL009 - Delivery assignment of serial number &1 must not be changed ?

  The SAP error message /SCWM/SERIAL009 indicates that there is an issue with the delivery assignment of a serial number in the Extended Warehouse Management (EWM) module. Specifically, the message states that the delivery assignment of the specified serial number must not be changed. This typically occurs when there is an attempt to modify the delivery assignment of a serial number that is already linked to a specific delivery or handling unit.
  Cause:
  
  Existing Assignment: The serial number is already assigned to a delivery, and the system does not allow changes to this assignment once it has been established.
  Status of Serial Number: The serial number may be in a status that does not permit changes, such as being part of a completed or closed delivery.
  Business Logic: The business process may dictate that once a serial number is assigned to a delivery, it should remain unchanged to maintain data integrity and traceability.
  
  Solution:
  
  Check Serial Number Assignment: Verify the current assignment of the serial number in question. You can do this by checking the serial number in the system to see which delivery it is currently assigned to.
  Review Delivery Status: Ensure that the delivery associated with the serial number is in a status that allows for changes. If the delivery is completed or closed, you may need to create a new delivery or adjust the process accordingly.
  Use Correct Transaction: If you need to change the assignment, ensure you are using the correct transaction or process flow that allows for such changes, if applicable.
  Consult Documentation: Review SAP documentation or your organization's internal guidelines regarding serial number management and delivery assignments to ensure compliance with business rules.
  Contact Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting with an SAP expert who can provide further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM that deal with serial numbers and deliveries, such as /SCWM/PRDI for production orders or /SCWM/DELIVERY for delivery processing.
  SAP Notes: Check for any SAP Notes related to serial number management and delivery assignments that may provide additional insights or solutions.
  Custom Development: If your organization has custom developments or enhancements related to serial number handling, ensure that these are functioning as intended and not causing conflicts.
