• What is the cause and solution for SAP error message VHUMI151 - HU &1 is not the highest hierarchy level, &2 is ?

  The SAP error message VHUMI151 indicates that the Handling Unit (HU) you are trying to process is not at the highest hierarchy level in the handling unit structure. This typically occurs when you are attempting to perform an operation (like packing, unpacking, or posting goods movements) on a handling unit that is not the top-level HU in its hierarchy.
  Cause:
  
  Hierarchy Structure: In SAP, handling units can be nested. For example, a handling unit can contain other handling units. The error message VHUMI151 suggests that the HU you are working with is a sub-HU and not the top-level HU.
  Incorrect Selection: You may have selected a lower-level HU instead of the highest-level HU for the operation you are trying to perform.
  
  Solution:
  
  
  Identify the Highest Level HU: You need to identify the highest-level handling unit in the hierarchy. You can do this by checking the handling unit structure in the SAP system.
  
  Use transaction code HU02 (Display Handling Unit) to view the hierarchy of handling units.
  Look for the parent handling unit that is at the top of the hierarchy.
  
  
  
  Perform Operation on the Correct HU: Once you have identified the highest-level HU, perform the operation on that HU instead of the sub-HU.
  
  
  Check for Nested HUs: If you need to perform operations on nested HUs, ensure that you are following the correct sequence of operations (e.g., unpacking the lower-level HUs before performing actions on the higher-level HU).
  
  
  Related Information:
  
  Handling Units (HUs): In SAP, handling units are used to manage packaging and logistics processes. They can represent physical packaging units and can be nested.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as:
  
  HU02: Display Handling Unit
  HU01: Create Handling Unit
  HU03: Change Handling Unit
  
  
  Documentation: Refer to SAP Help documentation for more details on handling units and their hierarchy management.
  
  By following these steps, you should be able to resolve the VHUMI151 error and successfully perform the desired operations on handling units in SAP.
