• What is the cause and solution for SAP error message /SCWM/DLV_SERIAL304 - Serial number &1 assigned to HU &2 (Split item only creatable via HU) ?

  The SAP error message /SCWM/DLV_SERIAL304 indicates that there is an issue with the handling unit (HU) and the serial number assignment in the context of split items in the Extended Warehouse Management (EWM) module. This error typically arises when you are trying to create or process a handling unit that is associated with a serial number, but the system is unable to do so due to the specific conditions of the item being processed.
  Cause:
  
  Serial Number Assignment: The error occurs when a serial number is already assigned to a handling unit (HU) that is being processed, and the system expects that the item can only be created or processed via the handling unit.
  Split Item Handling: The item you are trying to process is a split item, which means it is part of a larger quantity that has been divided into smaller quantities. The system requires that such items be handled through the handling unit that contains the serial number.
  Configuration Issues: There may be configuration settings in the EWM that dictate how serial numbers and handling units are managed, which could lead to this error if not set up correctly.
  
  Solution:
  
  Check Serial Number Assignment: Ensure that the serial number you are trying to assign is not already assigned to another handling unit or item. If it is, you may need to reassign or use a different serial number.
  Use Handling Units: If you are working with split items, ensure that you are processing them through the appropriate handling units. You may need to create or modify the handling unit to include the serial number correctly.
  Review Configuration: Check the configuration settings in the EWM for handling units and serial number management. Ensure that the settings align with your business processes and that they allow for the handling of split items with serial numbers.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed information on handling units and serial number management in EWM. This can provide insights into best practices and configuration settings.
