• What is the cause and solution for SAP error message L1428 - Plant / storage location &1/&2 has HU requirement and whse &3 is decentr. ?

  The SAP error message L1428 indicates that there is a requirement for handling units (HUs) in a specific plant and storage location, but the warehouse in question is decentralized. This error typically arises in the context of warehouse management (WM) and inventory management processes.
  Cause:
  
  Handling Unit Requirement: The plant/storage location combination specified in the error message has been configured to require handling units for inventory management.
  Decentralized Warehouse: The warehouse indicated is set up as a decentralized warehouse, which means that it operates independently from the central system. In decentralized setups, certain functionalities related to handling units may not be fully supported or may require specific configurations.
  
  Solution:
  To resolve this error, you can consider the following steps:
  
  
  Check Configuration:
  
  Verify the configuration settings for the plant and storage location in question. Ensure that the handling unit management settings are correctly defined.
  Check if the warehouse is indeed set up as decentralized and whether it supports handling unit management.
  
  
  
  Adjust Warehouse Settings:
  
  If the warehouse should support handling units, you may need to adjust the configuration to enable handling unit management for the decentralized warehouse.
  Alternatively, if handling units are not required for this warehouse, you may need to change the settings for the plant/storage location to not require handling units.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or consult with your SAP support team to understand the implications of handling unit management in decentralized warehouses and how to configure them properly.
  
  
  
  Testing:
  
  After making any changes, perform tests to ensure that the error is resolved and that the handling unit requirements are functioning as expected.

  SAP Notes and Support: Check SAP Notes for any known issues or patches related to this error message. SAP Support can provide additional guidance based on your specific system configuration.
