  The SAP error message /SCWM/SERIAL122 indicates that there is an issue with the assignment of a unique item identifier (serial number) to a handling unit (HU) in the SAP Extended Warehouse Management (EWM) system. Specifically, this error occurs when you attempt to assign a serial number that is already assigned to another handling unit.
  Cause:
  
  Duplicate Serial Number Assignment: The serial number you are trying to assign to a handling unit is already linked to another handling unit in the system.
  Incorrect Data Entry: There may have been a mistake in data entry, leading to the attempt to assign the same serial number to multiple handling units.
  System Configuration: The system may not be configured correctly to handle serial numbers, leading to conflicts.
  
  Solution:
  
  
  Check Existing Assignments: 
  
  Use transaction codes like /SCWM/HU or /SCWM/PR to check the handling units and their assigned serial numbers. Identify where the serial number is already assigned.
  
  
  
  Reassign Serial Number:
  
  If the serial number is indeed assigned to another handling unit and you need to reassign it, you may need to unassign it from the current handling unit first. This can be done through the appropriate transaction or program in EWM.
  
  
  
  Correct Data Entry:
  
  Ensure that the serial number you are trying to assign is unique and not already in use. Double-check the input data for any errors.
  
  
  
  Review System Configuration:
  
  If this issue occurs frequently, review the configuration settings related to serial number management in EWM. Ensure that the system is set up to handle serial numbers correctly.
  
  
  
  Consult Documentation:

  SAP Notes: Check SAP Notes for any known issues or patches related to serial number handling in EWM.
  User Roles and Authorizations: Ensure that the user has the necessary authorizations to perform actions related to handling units and serial numbers.
