• What is the cause and solution for SAP error message VL354 - Quantity change not permitted; &2 &3 are packed in shipment &1 ?

  The SAP error message VL354 ("Quantity change not permitted; &2 &3 are packed in shipment &1") typically occurs in the context of logistics and shipping processes within the SAP system. This error indicates that there is an attempt to change the quantity of items that have already been packed into a shipment, which is not allowed.
  Cause:
  
  Packed Items: The items you are trying to modify (increase or decrease the quantity) have already been packed into a shipment. Once items are packed, their quantities are locked to maintain the integrity of the shipment.
  Shipment Status: The shipment may be in a status that does not allow for changes to the packed quantities. For example, if the shipment is already in a "shipped" or "delivered" status, changes to the packed quantities are typically restricted.
  Document Flow: There may be related documents (like delivery documents) that are already created based on the packed quantities, which prevents changes.
  
  Solution:
  
  Unpack the Shipment: If you need to change the quantity, you may need to unpack the items from the shipment first. This can usually be done through the shipment processing transaction in SAP.
  Adjust the Delivery: If the shipment is linked to a delivery, you may need to adjust the delivery document first before making changes to the shipment.
  Check Shipment Status: Ensure that the shipment is in a status that allows for changes. If it is already completed or in a final status, you may need to create a new shipment or delivery.
  Consult with Logistics Team: If you are unsure about the implications of unpacking or changing quantities, consult with your logistics or warehouse management team to ensure that you follow the correct procedures.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as VL02N (Change Outbound Delivery), VL03N (Display Outbound Delivery), and VT01N (Create Shipment) to manage shipments effectively.
  SAP Documentation: Refer to SAP Help documentation for detailed guidance on handling shipments and deliveries, as well as the implications of changing packed quantities.
  User Authorizations: Ensure that you have the necessary authorizations to make changes to shipments and deliveries, as restrictions may be in place based on user roles.
  
  By following these steps, you should be able to resolve the VL354 error and manage your shipment quantities effectively.
