• What is the cause and solution for SAP error message /SCWM/HUFUNCTIONS190 - Handling unit &1 is already assigned to this delivery ?

  The SAP error message /SCWM/HUFUNCTIONS190 indicates that a handling unit (HU) is already assigned to a delivery, and therefore cannot be assigned to another delivery or operation. This error typically occurs in the context of warehouse management and logistics processes within SAP Extended Warehouse Management (EWM).
  Cause:
  
  Duplicate Assignment: The handling unit you are trying to assign is already linked to another delivery. This can happen if the HU was previously processed or if there was an attempt to reassign it without proper unassignment.
  System Configuration: There may be specific configurations or settings in the system that prevent the reassignment of handling units once they are linked to a delivery.
  Incomplete Processing: The handling unit may be in a state that does not allow it to be reassigned, such as being part of a completed or partially completed delivery process.
  
  Solution:
  
  Check Current Assignment: Use transaction codes like /SCWM/HU or /SCWM/PR to check the current status and assignment of the handling unit. Ensure that it is not linked to any other delivery.
  Unassign the Handling Unit: If the handling unit is indeed assigned to another delivery and you need to reassign it, you may need to unassign it first. This can typically be done through the appropriate transaction or function in SAP EWM.
  Review Delivery Status: Ensure that the delivery to which the handling unit is currently assigned is in a status that allows for changes. If the delivery is completed or in a locked state, you may need to take additional steps to unlock or modify it.
  Consult Documentation: Review SAP documentation or help files related to handling units and delivery processes to ensure compliance with best practices.
  Contact Support: If the issue persists and you cannot resolve it, consider reaching out to your SAP support team or consulting with an SAP expert for further assistance.
