• What is the cause and solution for SAP error message /SCWM/RFID013 - WT &1 is already assigned to resource &2 ?

  The SAP error message /SCWM/RFID013 WT &1 is already assigned to resource &2 typically occurs in the context of the SAP Extended Warehouse Management (EWM) system, particularly when dealing with Radio Frequency Identification (RFID) and warehouse tasks (WT).
  Cause:
  This error indicates that a specific Warehouse Task (WT) identified by &1 is already assigned to a resource (such as a user or a device) identified by &2. This can happen due to several reasons:
  
  Concurrent Assignment: The same WT is being attempted to be assigned to multiple resources simultaneously.
  Session Overlap: If a user or device is trying to process the same WT in different sessions or transactions.
  System Configuration: There may be issues with the configuration of the resource management or task assignment logic in the EWM system.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Resource Assignment:
  
  Verify which resource is currently assigned to the WT. You can do this by checking the status of the WT in the EWM system.
  Use transaction codes like /SCWM/PRDI (for processing RF transactions) or /SCWM/WT (for managing warehouse tasks) to view the current assignments.
  
  
  
  Release the WT:
  
  If the WT is stuck or incorrectly assigned, you may need to release it from the current resource. This can often be done through the EWM interface or by using specific transaction codes to unassign the WT.
  
  
  
  Avoid Concurrent Processing:
  
  Ensure that the same WT is not being processed by multiple users or devices at the same time. Implementing proper locking mechanisms or user training can help mitigate this issue.
  
  
  
  Check System Logs:
  
  Review system logs for any additional error messages or warnings that might provide more context about the issue.
  
  
  
  Configuration Review:
  
  If the problem persists, review the configuration settings related to resource management and task assignment in the EWM system. Ensure that the settings align with your operational processes.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to EWM and RFID for any known issues or patches that might address this error.
  
  
  
  Contact SAP Support:
  
  If you are unable to resolve the issue, consider reaching out to SAP support for further assistance. They may provide insights based on the specific version of your EWM system and any known issues.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in EWM for managing warehouse tasks and resources.
  SAP Notes: Check SAP Notes for any updates or patches that might address this specific error.
  User Training: Ensure that users are trained on the proper procedures for assigning and processing warehouse tasks to minimize errors.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
