• What is the cause and solution for SAP error message LT258 - No warehouse stocks must exist when lean WM is activated ?

  The SAP error message LT258 ("No warehouse stocks must exist when lean WM is activated") typically occurs in the context of Lean Warehouse Management (Lean WM) in SAP. This error indicates that there are existing stocks in the warehouse that need to be cleared before you can activate Lean WM for that warehouse.
  Cause:
  The primary cause of this error is that Lean WM cannot be activated for a warehouse that currently has stock. Lean WM is designed for environments where inventory management is simplified, and it does not support the management of stock in the same way as traditional Warehouse Management (WM). Therefore, if there are any stocks present in the warehouse, the system will prevent the activation of Lean WM.
  Solution:
  To resolve this error, you need to ensure that there are no stocks in the warehouse before activating Lean WM. Here are the steps you can take:
  
  
  Check Stock Levels: Use transaction codes like MMBE (Stock Overview) or MB52 (List Warehouse Stocks on Hand) to check if there are any stocks in the warehouse.
  
  
  Clear Existing Stocks:
  
  Transfer Stock: Move the stock to another warehouse or storage location using transfer postings (transaction code MB1B or MIGO).
  Remove Stock: If applicable, you can also remove stock through stock adjustments or write-offs.
  Complete Open Deliveries: Ensure that all open deliveries or stock movements are completed.
  
  
  
  Deactivate Lean WM: If you do not need Lean WM, you can consider deactivating it for the warehouse. This can be done in the configuration settings.
  
  
  Activate Lean WM: Once all stocks have been cleared, you can proceed to activate Lean WM for the warehouse.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MIGO, MB1B, MMBE, and MB52 for stock management.
  Configuration Settings: Review the configuration settings for Lean WM in the SAP IMG (Implementation Guide) under Logistics Execution > Warehouse Management > Lean Warehouse Management.
  Documentation: Refer to SAP Help documentation for detailed steps on activating Lean WM and managing warehouse stocks.
  
  By following these steps, you should be able to resolve the LT258 error and successfully activate Lean WM for your warehouse.
