• What is the cause and solution for SAP error message /SCWM/RFID003 - EPC &1 Already Exists ?

  The SAP error message /SCWM/RFID003 EPC &1 Already Exists typically occurs in the context of SAP Extended Warehouse Management (EWM) when dealing with RFID (Radio Frequency Identification) technology. This error indicates that the EPC (Electronic Product Code) you are trying to register or process already exists in the system.
  Cause:
  
  
  Duplicate EPC: The primary cause of this error is that the EPC you are trying to use has already been registered in the system. This can happen if:
  
  The same item is scanned multiple times.
  There is a data entry error where the same EPC is being used for different items.
  The EPC was previously processed and not properly cleared from the system.
  
  
  
  System Configuration: There may be issues with how the system is configured to handle EPCs, leading to conflicts or mismanagement of existing EPCs.
  
  
  Solution:
  
  
  Check Existing EPCs: 
  
  Use transaction codes or reports in SAP EWM to check the existing EPCs in the system. You can look for the EPC in the relevant tables or use the RFID monitoring tools provided by SAP.
  If the EPC is indeed already registered, determine if it is still valid or if it can be reused.
  
  
  
  Clear or Update Existing EPC:
  
  If the EPC is no longer valid or should not be in the system, you may need to delete or deactivate it. This can involve using specific transactions or reports to manage EPCs.
  If the EPC is valid but needs to be updated, ensure that the correct information is being used.
  
  
  
  Review System Configuration:
  
  Check the configuration settings related to RFID and EPC management in SAP EWM. Ensure that the system is set up correctly to handle EPCs and that there are no conflicting settings.
  
  
  
  Consult Documentation:
