  The SAP error message VHUDLV100 indicates that there is an issue with handling units in the system, specifically that there can only be one highest-level handling unit for a given handling unit hierarchy. This error typically arises in the context of logistics and warehouse management when dealing with handling units (HUs) in SAP.
  Cause:
  The error occurs when the system detects that there are multiple highest-level handling units defined for a single handling unit hierarchy. In SAP, a handling unit can be a packaging unit that contains other handling units, and the system expects a clear hierarchy where only one handling unit is at the top level.
  Possible Causes:
  
  Duplicate Handling Units: There may be multiple handling units marked as the highest level in the hierarchy.
  Incorrect Hierarchy Structure: The structure of handling units may not be correctly defined, leading to confusion in the hierarchy.

  Solution:
  To resolve the error, you can take the following steps:

  Ensure that there is only one highest-level handling unit.
  
  
  
  Correct the Hierarchy:
  
  If you find multiple highest-level handling units, you will need to adjust the hierarchy. This may involve reassigning handling units or restructuring the hierarchy to ensure that only one unit is at the top level.
  
  
  
  Data Consistency Check:
  
  Run consistency checks on handling units to identify any discrepancies. You can use transaction LX02 (Inventory Management) or similar tools to check for inconsistencies.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or help files related to handling units and their hierarchy to ensure you are following the correct procedures.
