• What is the cause and solution for SAP error message /SCWM/RF_EN850 - User &1 logged on as resource &2 with device &3 ?

  The SAP error message /SCWM/RF_EN850 typically indicates an issue related to the user and resource configuration in the SAP Extended Warehouse Management (EWM) system, particularly when using Radio Frequency (RF) devices. The message states that a user is logged on as a specific resource with a particular device, which can lead to conflicts or issues in the system.
  Cause:
  
  User Already Logged In: The user is already logged in to the system using the specified resource and device. This can happen if the user did not log out properly or if there is a session timeout.
  Resource Configuration: The resource (e.g., a forklift or a picking device) may be configured to allow only one user at a time, and the current user is trying to log in again without logging out the previous session.
  Device Assignment: The device may be incorrectly assigned or configured in the system, leading to conflicts when multiple users attempt to access it.
  
  Solution:
  
  Log Out the User: Ensure that the user is logged out from the RF device. This can often be done through the RF device interface or by using the SAP GUI to terminate the session.
  Check Resource Status: Verify the status of the resource in the system. If the resource is still active with the previous user, you may need to manually log out the user or reset the resource.
  Review Device Configuration: Check the configuration of the RF device and the resource in the SAP EWM system. Ensure that the settings allow for the intended usage and that there are no restrictions preventing the user from logging in.
  Session Management: Implement better session management practices to ensure users log out properly after their tasks are completed. This can help prevent similar issues in the future.
  Consult Documentation: Refer to SAP documentation or support for specific instructions related to your version of EWM, as there may be additional steps or considerations based on your system configuration.

  SAP Notes: Check for any relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
