• What is the cause and solution for SAP error message /SCWM/TO_WHR045 - Requested quantity for &1, &2 reduced by &3, &4, due to blocked HU ?

  The SAP error message /SCWM/TO_WHR045 indicates that the requested quantity for a handling unit (HU) has been reduced due to the fact that the handling unit is blocked. This typically occurs in the context of warehouse management processes within SAP Extended Warehouse Management (EWM).
  Cause:
  The error message is triggered when:
  
  A handling unit (HU) is blocked for some reason, which prevents the full requested quantity from being processed.
  The blocking could be due to various reasons, such as:
  
  Quality inspection status (the HU is under inspection).
  Damage or other issues that have led to the HU being marked as blocked.
  Manual blocking by warehouse personnel for inventory management reasons.
  
  
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Check the Status of the Handling Unit:
  
  Use transaction codes like /SCWM/HU to display the handling unit and check its status.
  Look for any indicators that show the HU is blocked.
  
  
  
  Identify the Reason for Blocking:
  
  Investigate why the HU is blocked. This could involve checking quality inspection results, damage reports, or any manual entries made by warehouse staff.
  
  
  
  Unblock the Handling Unit:
  
  If the blocking is due to a quality inspection, ensure that the inspection is completed and the HU is released.
  If the HU is blocked for other reasons, follow the appropriate procedures to unblock it. This may involve updating the HU status in the system.
  
  
  
  Adjust the Transfer Order:
  
  If the HU cannot be unblocked, you may need to adjust the transfer order (TO) to reflect the available quantity that can be processed.
  
  
  
  Consult Documentation or Support:
  
  If you are unsure about the blocking reason or how to resolve it, consult your internal documentation or reach out to SAP support for assistance.
  
  
  
  Related Information:
  
  Handling Units (HUs): In SAP EWM, handling units are used to manage inventory at a more granular level, allowing for better tracking and management of goods.
  Quality Management (QM): If the blocking is related to quality inspection, ensure that your quality management processes are well-defined and that staff are trained on how to handle blocked HUs.
  Warehouse Management Processes: Familiarize yourself with the overall warehouse management processes in SAP EWM to understand how HUs are managed and the implications of blocking.
  
  By following these steps, you should be able to identify the cause of the error and take appropriate action to resolve it.
