• What is the cause and solution for SAP error message /SCWM/RF_EN120 - Insert highest-level HU ?

  The SAP error message /SCWM/RF_EN120 Insert highest-level HU typically occurs in the context of handling units (HUs) in the SAP Extended Warehouse Management (EWM) module. This error indicates that the system expects the user to insert a highest-level handling unit (HU) when performing certain operations, such as picking, packing, or transferring goods.
  Cause:
  
  Hierarchy Requirement: The operation being performed requires a highest-level HU to be specified. This is often the case when dealing with nested handling units, where a higher-level HU contains lower-level HUs.
  Incorrect HU Selection: The user may have selected a lower-level HU instead of the required highest-level HU.
  Configuration Issues: There may be configuration settings in the EWM system that dictate how HUs should be handled, which could lead to this error if not set up correctly.
  
  Solution:
  
  Identify the Highest-Level HU: Ensure that you are selecting the correct highest-level HU for the operation. You may need to check the HU hierarchy to find the appropriate HU.
  Use the Correct Transaction: Make sure you are using the correct transaction or process that allows for the handling of HUs. If you are in a picking or packing process, ensure that you are following the correct steps.
  Check HU Status: Verify the status of the HUs involved. If the highest-level HU is not in a suitable status (e.g., it is blocked or not available), you may need to resolve that issue first.
  Review Configuration: If the issue persists, review the configuration settings related to handling units in the EWM system. This may involve checking the settings for HU management, packing, and handling unit types.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling units and the processes you are working with.
  
  Related Information:
  
  Handling Units (HUs): In SAP EWM, HUs are used to manage the physical packaging of goods. They can be nested, meaning that a higher-level HU can contain one or more lower-level HUs.
  EWM Processes: Understanding the specific EWM processes (like inbound/outbound delivery, picking, packing) can help in troubleshooting HU-related issues.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling units in EWM.
  
  If the problem continues after trying the above solutions, it may be beneficial to consult with your SAP support team or a consultant who specializes in SAP EWM for further assistance.
