  The SAP error message HUFUNCTIONS190 indicates that a handling unit (HU) is already assigned to a delivery, and therefore cannot be assigned again to another delivery or operation. This error typically occurs during processes such as goods movement, delivery creation, or when trying to reassign handling units.

  Duplicate Assignment: The handling unit you are trying to assign is already linked to a different delivery.
  Incorrect Process Flow: The handling unit may not have been properly processed or released in the previous transaction.
  System Configuration: There may be specific configurations or settings in the system that prevent the reassignment of handling units.
  
  Solution:
  
  
  Check Current Assignment:
  
  Use transaction code HU02 (Display Handling Unit) to check the current assignment of the handling unit. This will show you which delivery the handling unit is currently assigned to.

  Ensure that the handling unit is processed correctly in the previous steps. If it was supposed to be delivered or moved, ensure that those transactions are completed successfully.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation or your organization's internal guidelines for handling units to ensure compliance with the expected processes.
  
  
  
  Check for System Issues:
