Smart SAP Assistant

• What is the cause and solution for SAP error message /SCWM/DS_CORE278 - Planner &1 is assigned to user &2 and cannot be assigned to &3. ?

  The SAP error message /SCWM/DS_CORE278 indicates that there is a conflict in the assignment of a planner to a user in the SAP Extended Warehouse Management (EWM) system. Specifically, it states that a planner (identified as &1) is already assigned to a user (identified as &2) and cannot be assigned to another user (identified as &3).
  Cause:
  This error typically occurs due to the following reasons:
  
  Single Assignment Rule: The system is configured to allow only one user to be assigned to a specific planner at any given time. If a planner is already assigned to one user, attempting to assign the same planner to another user will trigger this error.
  Configuration Settings: The settings in the system may enforce strict assignment rules for planners, which can lead to this error if not managed properly.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Current Assignments:
  
  Verify the current assignments of the planner in question. You can do this by navigating to the relevant configuration or master data area in SAP EWM where planner assignments are managed.
  
  
  
  Reassign the Planner:
  
  If you need to assign the planner to a different user, you will first need to remove the existing assignment from the current user (&2). This can typically be done in the user management or planner assignment section of the EWM configuration.
  
  
  
  Update User Assignments:
  
  After removing the assignment from the current user, you can then proceed to assign the planner to the new user (&3).
  
  
  
  Review Configuration:
  
  If this assignment behavior is not desired, consider reviewing the configuration settings related to planner assignments. You may want to adjust the settings to allow multiple users to be assigned to the same planner if that fits your business process.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help resources for more detailed instructions on managing planner assignments in EWM.
  
  
  
  Related Information:
  
  Transaction Codes: You may need to use specific transaction codes related to user management and planner assignments in EWM, such as /SCWM/PLNR for planner management.
  User Roles and Authorizations: Ensure that the users involved have the necessary roles and authorizations to make changes to planner assignments.
  SAP Notes: Check for any relevant SAP Notes that may address this issue or provide additional guidance.
  
  By following these steps, you should be able to resolve the error and manage planner assignments effectively in your SAP EWM system.
