• What is the cause and solution for SAP error message /SCWM/UI_PACKING164 - Quitting of storage control only allowed for top HU ?

  The SAP error message /SCWM/UI_PACKING164 indicates that there is an issue with the handling unit (HU) in the context of warehouse management, specifically related to the quitting of storage control. The message states that quitting of storage control is only allowed for the top handling unit (HU). 
  Cause:
  This error typically occurs when you attempt to quit or release a handling unit that is not the top-level HU in a hierarchical structure. In SAP Extended Warehouse Management (EWM), handling units can be nested, meaning that one HU can contain other HUs. The system restricts the quitting of storage control to only the top-level HU to maintain the integrity of the inventory and the warehouse processes.
  Solution:
  To resolve this error, you should ensure that you are attempting to quit the storage control for the top-level handling unit. Here are the steps you can take:
  
  
  Identify the Top Handling Unit: Check the hierarchy of the handling units involved. You can do this by using transaction codes like /SCWM/HU to display the handling unit and its structure.
  
  
  Quit Storage Control for Top HU: Once you have identified the top handling unit, perform the action to quit the storage control specifically for that HU.
  
  
  Check for Nested HUs: If you have nested handling units, ensure that any actions you are trying to perform are appropriate for the level of the HU you are working with.
  
  
  Review Documentation: If you are unsure about the handling unit structure or the process, refer to the SAP documentation or your organization's internal guidelines on handling units and warehouse management processes.
  
  
  Consult with SAP Support: If the issue persists or if you need further assistance, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or additional guidance.

  SAP EWM Configuration: Ensure that your EWM system is configured correctly for handling units and that all relevant settings are in place.
