• What is the cause and solution for SAP error message /SCWM/UI_TO_CONF025 - Negative HU differences are not allowed ?

  The SAP error message /SCWM/UI_TO_CONF025 Negative HU differences are not allowed typically occurs in the context of handling units (HUs) in the SAP Extended Warehouse Management (EWM) module. This error indicates that there is an attempt to process a handling unit (HU) with a negative difference, which is not permitted in the system.
  Cause:
  
  Negative Handling Unit Quantity: The error usually arises when there is an attempt to confirm a transfer order (TO) or handling unit that results in a negative quantity. This can happen if the system is trying to reduce the quantity of an HU below zero.
  Incorrect Data Entry: Manual entry errors during the confirmation process can lead to discrepancies in the expected quantities.
  System Configuration: The system may be configured to disallow negative quantities for handling units, which is a common practice to maintain inventory integrity.
  
  Solution:
  
  Check Handling Unit Quantities: Review the handling unit involved in the transaction. Ensure that the quantities are correct and that you are not trying to confirm a quantity that would result in a negative value.
  Adjust Transfer Order: If the transfer order is incorrect, you may need to adjust it to ensure that the quantities being confirmed are valid and do not lead to negative values.
  Review Confirmation Process: Ensure that the confirmation process is being followed correctly. If you are using a mobile device or a specific interface, verify that the data being entered is accurate.
  System Configuration: If necessary, consult with your SAP Basis or EWM configuration team to review the settings related to handling units and negative quantities. They may need to adjust the configuration if it is too restrictive for your business processes.
  Consult Documentation: Refer to SAP documentation or help resources for more detailed guidance on handling units and transfer order confirmations.
