• What is the cause and solution for SAP error message VHUMI160 - HU &1 does not only contain materials but also HU &2 ?

  The SAP error message VHUMI160 indicates that there is an issue with handling units (HUs) in the system. Specifically, the message states that the handling unit (HU) identified by &1 does not only contain materials but also another handling unit (HU) identified by &2. This situation typically arises during processes such as goods movements, inventory management, or when trying to pack or unpack handling units.
  Cause:
  
  Nested Handling Units: The error occurs when a handling unit is expected to contain only materials (stock items) but instead contains another handling unit. This can happen if the system is set up to allow nested handling units, but the current operation does not support it.
  Incorrect Packing Configuration: The packing configuration may not be set up correctly, leading to the system not recognizing the nested structure.
  Data Entry Error: There may have been a mistake in the data entry or packing process, where a handling unit was incorrectly packed into another handling unit.
  
  Solution:
  
  Check Handling Unit Structure: Review the structure of the handling units involved. Ensure that HU &1 is intended to contain only materials and not another handling unit. If it is supposed to contain another HU, you may need to adjust your packing strategy.
  Unpack the Handling Unit: If HU &1 contains HU &2, you may need to unpack HU &1 first before proceeding with the operation. This can typically be done using the unpacking transaction in SAP.
  Adjust Packing Instructions: If the packing instructions or configuration allow for nested handling units, ensure that the process you are trying to execute supports this. You may need to adjust the configuration in the system.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling units and packing processes. This can provide insights into how to manage nested handling units effectively.
  Contact SAP Support: If the issue persists and you cannot find a resolution, consider reaching out to SAP support for assistance. They can provide more detailed troubleshooting based on your specific system configuration.
