This error typically arises in the context of planning or inventory management processes where negative quantities are not allowed for certain operations.

  Adjust Inventory: If you find that there are negative quantities due to incorrect postings, you may need to:
  
  Reverse or correct the transactions that led to the negative quantity.

  Review Configuration: If negative quantities are expected in your business process, you may need to review the configuration settings in SAP to allow for such scenarios. However, this should be done with caution and typically requires consultation with a functional consultant or SAP expert.
