• What is the cause and solution for SAP error message /SCWM/WHO126 - Maximum number of items per HU reached ?

  The SAP error message /SCWM/WHO126 Maximum number of items per HU reached typically occurs in the SAP Extended Warehouse Management (EWM) module when you attempt to add more items to a Handling Unit (HU) than the system allows. This limit is defined in the system settings and is meant to ensure that HUs do not become overloaded or unmanageable.
  Cause:
  
  Configuration Limit: The maximum number of items that can be packed into a single HU is defined in the system configuration. If you try to add more items than this limit, the error will be triggered.
  Item Type Restrictions: Certain item types may have specific restrictions on how many can be packed into a single HU.
  Warehouse Process: The warehouse process you are executing may have specific rules or configurations that limit the number of items per HU.
  
  Solution:
  
  
  Check Configuration: 
  
  Go to the EWM configuration settings and check the maximum number of items allowed per HU. This can usually be found in the settings for Handling Units or Packaging.
  You can adjust this limit if necessary, but be cautious as increasing it may lead to operational inefficiencies.
  
  
  
  Review the HU: 
  
  Check the current contents of the HU to see how many items are already packed. If the HU is already at its limit, you will need to either:
  
  Create a new HU for the additional items.
  Remove some items from the current HU if applicable.
  
  
  
  
  
  Adjust Packing Strategy: 
  
  If your warehouse processes allow, consider adjusting your packing strategy to distribute items across multiple HUs rather than trying to pack too many into one.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or help resources for specific guidelines on handling HUs and packing strategies.
  
  
  
  Contact Support: 
  
  If you are unable to resolve the issue through configuration or process adjustments, consider reaching out to your SAP support team for further assistance.
