  The SAP error message HUDIALOG143 indicates that a handling unit (HU) is already reserved for a specific plant order. This typically occurs in scenarios where inventory management and handling units are involved, such as in warehouse management or production processes.
  Cause:
  The error arises when you attempt to reserve or use a handling unit that is already linked to another plant order. This can happen due to:
  
  Concurrent attempts to reserve the same handling unit for different orders.
  Incorrect handling unit management or inventory status.

  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check the Handling Unit Status:
  
  Use transaction code HU03 (Display Handling Unit) to check the status of the handling unit in question. Ensure that it is not currently reserved for another order.

  Check for Concurrent Processes:
  
  Ensure that no other users or processes are trying to reserve the same handling unit simultaneously. Coordination among users may be necessary.
