  The SAP error message LF197, which states "Negative values are not allowed for the current quantity," typically occurs in the context of inventory management or logistics when a user attempts to process a transaction that involves a negative quantity. This can happen in various scenarios, such as during goods movements, stock transfers, or inventory adjustments.
  Cause:
  
  Negative Quantity Entry: The most common cause is that a user is trying to enter a negative quantity for a material movement, which is not allowed in certain contexts (e.g., when the system expects a positive quantity).
  Incorrect Document Type: The document type being used may not support negative quantities. For example, certain goods receipt or goods issue transactions may not allow negative values.

  Check Quantity Entry: Ensure that the quantity being entered is positive. If you intended to reduce stock, use the appropriate transaction type that allows for a goods issue or stock reduction.
  Review Document Type: Verify that you are using the correct document type for the transaction. If you need to perform a negative stock movement, ensure that the document type supports it.
  Adjust Stock Levels: If you need to adjust stock levels, consider using a stock adjustment transaction that allows for negative quantities, such as a stock transfer or inventory adjustment.
  Consult Configuration: If you believe the configuration may be causing the issue, consult with your SAP administrator or a functional consultant to review the settings related to inventory management and stock handling.
  Check Material Master Data: Ensure that the material master data is correctly set up, including the valuation type and stock type settings.
