  The SAP error message LF185, which states "Handling unit is not assigned. Use other transaction," typically occurs in the context of handling units (HUs) in the SAP Extended Warehouse Management (EWM) or Logistics Execution (LE) modules. This error indicates that the system cannot find a handling unit that is expected to be assigned to a particular transaction or process.
  Cause:
  
  Unassigned Handling Unit: The handling unit you are trying to work with has not been assigned to the relevant document (e.g., delivery, transfer order).
  Incorrect Transaction: You may be using a transaction that is not appropriate for the handling unit you are trying to process.
  Data Inconsistency: There may be inconsistencies in the data, such as missing or incorrect entries in the handling unit master data.
  Status Issues: The handling unit may be in a status that does not allow it to be processed (e.g., it may be blocked or completed).
  
  Solution:
  
  
  Check Handling Unit Assignment:
  
  Use transaction codes like HU02 (Display Handling Unit) or HU03 (Change Handling Unit) to check if the handling unit is correctly assigned to the relevant document.
  Ensure that the handling unit is linked to the correct delivery or transfer order.
  
  
  
  Use the Correct Transaction:

  Reassign Handling Unit:
  
  If the handling unit is not assigned, you may need to reassign it using the appropriate transaction (e.g., HU02 or VL02N for deliveries).
