  The SAP error message SE891, which states "Combination negative price and negative quantity not allowed," typically occurs in the context of pricing and inventory management within SAP. This error indicates that there is an attempt to process a transaction where both the price and quantity are negative, which is not permissible in SAP's business logic.
  Cause:

  Review Transaction Data: Check the transaction that triggered the error. Ensure that the price and quantity are set correctly. If you are processing a return, ensure that the pricing logic is correctly applied.
  Adjust Pricing or Quantity: If the transaction is valid, consider adjusting either the price or the quantity to avoid the negative combination. For example, if you are returning an item, you might need to set the price to a positive value or adjust the quantity to reflect the correct return scenario.
  Check Configuration: Review the pricing procedure and inventory management settings in your SAP configuration. Ensure that the system is set up to handle returns and discounts correctly without allowing invalid combinations.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidelines on handling negative prices and quantities in your version of SAP.
