• What is the cause and solution for SAP error message /SCWM/L3879 - Stock has outbound delivery reference; UoM cannot be changed ?

  The SAP error message /SCWM/L3879 Stock has outbound delivery reference; UoM cannot be changed typically occurs in the context of SAP Extended Warehouse Management (EWM) when you attempt to change the unit of measure (UoM) for stock that is already referenced in an outbound delivery. This situation arises because the system prevents changes to stock that is tied to an active outbound delivery to maintain data integrity and avoid inconsistencies in the delivery process.
  Cause:
  
  Outbound Delivery Reference: The stock you are trying to modify has an outbound delivery reference, meaning it is already allocated for shipment to a customer or another location.
  Unit of Measure Change: You are attempting to change the unit of measure for this stock, which is not allowed while it is still linked to an outbound delivery.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Remove the Outbound Delivery Reference:
  
  If possible, you can cancel or delete the outbound delivery that references the stock. This will allow you to change the UoM.
  Navigate to the outbound delivery in SAP and check if it can be canceled or if the stock can be unallocated.
  
  
  
  Change the UoM Before Delivery Creation:
  
  Ensure that any necessary changes to the UoM are made before the stock is allocated to an outbound delivery. This may involve adjusting stock levels or creating new stock with the desired UoM.
  
  
  
  Create a New Stock with the Desired UoM:
  
  If changing the UoM is essential, consider creating new stock in the desired UoM and transferring the inventory accordingly, if applicable.
  
  
  
  Consult with Logistics or Warehouse Management Team:
  
  If you are unsure about the implications of canceling an outbound delivery or changing stock, 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 /SCWM/PRDI (for stock management) and /SCWM/OD (for outbound delivery processing).
  Documentation: Review SAP documentation or help files related to stock management and outbound delivery processes in EWM for more detailed guidance.
  User Roles and Permissions: Ensure that you have the necessary permissions to make changes to stock and outbound deliveries in the system.
