Smart SAP Assistant

• What is the cause and solution for SAP error message WRF_APC621 - Enter a non-negative basic purchasing price (your entry: &1) ?

  The SAP error message:
  WRF_APC621: Enter a non-negative basic purchasing price (your entry: &1)
  
  Cause:
  This error occurs when you enter a negative value for the basic purchasing price in a purchasing document or material master record. The system expects the basic purchasing price to be zero or a positive number, as negative prices are not allowed in standard SAP pricing conditions or material valuation.
  
  Explanation:
  
  The basic purchasing price is the price at which a material is procured.
  Entering a negative price is logically inconsistent because it would imply the vendor pays you to take the material, which is not supported.
  This validation is enforced to maintain data integrity and correct valuation.
  
  
  Solution:
  
  Check the price entered in the purchasing document (e.g., Purchase Order, Info Record) or material master.
  Correct the price to a non-negative value (zero or positive).
  If you intended to enter a discount or rebate, these should be handled via condition records or pricing procedures, not by entering a negative basic price.
  Review the pricing procedure and condition types to ensure discounts/rebates are applied correctly.
  
  
  Related Information:
  
  Transaction codes where this might occur: ME21N (Create PO), ME22N (Change PO), MM02 (Change Material Master)
  Pricing conditions and procedures are maintained in SPRO ? Materials Management ? Purchasing ? Conditions.
  For handling discounts, use condition types like PB00 (Price), RA01 (Discount), etc.
  SAP Note or documentation on pricing and valuation might provide additional guidance.
