• What is the cause and solution for SAP error message L3889 - Pick HU was created internally ?

  The SAP error message L3889, which states "Pick HU was created internally," typically occurs in the context of handling handling units (HUs) in warehouse management processes. This message indicates that a handling unit (HU) was created automatically by the system during the picking process, rather than being created manually by a user.
  Cause:
  
  Automatic Handling Unit Creation: The system is configured to automatically create handling units during certain processes, such as picking or goods movement. This can happen if the configuration settings for handling units in the warehouse management module are set to allow for automatic creation.
  Warehouse Management Settings: The settings in the warehouse management (WM) module may dictate that HUs are created automatically based on specific criteria, such as the type of material, storage type, or picking strategy.
  User Actions: Sometimes, the error can be triggered by user actions that lead to the automatic creation of HUs, such as using a specific transaction or process that is designed to create HUs automatically.
  
  Solution:
  
  Review Configuration: Check the configuration settings in the Warehouse Management module to understand how handling units are being created. You may need to adjust the settings if you want to change the behavior of HU creation.
  Manual HU Creation: If you need to create handling units manually, ensure that you are following the correct procedures and using the appropriate transactions to do so.
  Check User Authorizations: Ensure that the user has the necessary authorizations to create handling units manually if that is the desired approach.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling units and the relevant configuration settings.
  Debugging: If the issue persists and is causing operational problems, consider debugging the process to identify any underlying issues or misconfigurations.
