• What is the cause and solution for SAP error message /SCWM/L3898 - TU &1 does not allow negative stock figures ?

  The SAP error message /SCWM/L3898 TU &1 does not allow negative stock figures typically occurs in the SAP Extended Warehouse Management (EWM) module when there is an attempt to process a Transfer Order (TO) or Handling Unit (HU) that would result in negative stock levels. This can happen during various operations, such as picking, putaway, or stock transfers.
  Cause:
  
  Negative Stock Configuration: The system is configured to disallow negative stock levels for the specific storage type or handling unit. This is a common setting in many warehouses to prevent stock discrepancies.
  Incorrect Stock Levels: The stock levels in the system may not reflect the actual physical stock, leading to attempts to process transactions that would result in negative stock.
  Transfer Order Issues: The transfer order may be attempting to move more stock than is available in the specified location or handling unit.
  
  Solution:
  
  Check Stock Levels: Verify the stock levels for the handling unit or storage location in question. Ensure that there is sufficient stock available to fulfill the transfer order or operation.
  Adjust Stock: If there are discrepancies, you may need to perform stock adjustments to correct the inventory levels. This can be done through inventory management transactions.
  Review Configuration: If negative stock is required for your business processes, consider reviewing the configuration settings in the warehouse management system. You can allow negative stock for specific storage types or handling units if necessary, but this should be done with caution.
  Correct Transfer Orders: If the transfer order is incorrect, you may need to adjust or cancel it and create a new one with the correct quantities.
  Consult Documentation: Refer to SAP documentation or consult with your SAP support team for specific configuration settings related to negative stock handling.
  
  Related Information:
  
  Transaction Codes: You may use transaction codes like /SCWM/TO for managing transfer orders or /SCWM/HU for handling units to check and manage stock levels.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling negative stock scenarios.
  User Exits and BAdIs: If your business process requires specific handling of stock levels, consider implementing user exits or Business Add-Ins (BAdIs) to customize the behavior of the system.
  
  By following these steps, you should be able to resolve the error and ensure that your stock levels are accurately reflected in the system.
