Smart SAP Assistant

• What is the cause and solution for SAP error message WRF_APC620 - Enter a non-negative net/net purchasing price (your entry: &1) ?

  The SAP error message:
  WRF_APC620 Enter a non-negative net/net purchasing price (your entry: &1)
  typically occurs in the context of SAP Materials Management (MM) or SAP Logistics Invoice Verification when dealing with purchasing prices, invoice verification, or price determination.
  
  Cause
  
  The system expects a net purchasing price (price without tax) that is zero or positive.
  The entered price is negative, which is not allowed.
  This can happen during:
  
  Invoice verification when entering the invoice price.
  Purchase order price maintenance.
  Price determination in automatic price updates.
  
  
  The system validates the price field and throws this error if the price is less than zero.
  
  
  Solution
  
  Check the price entered in the relevant transaction (e.g., MIRO, ME21N, ME22N).
  Ensure that the net purchasing price is zero or positive.
  If a discount or rebate is to be applied, it should be handled via the appropriate fields (e.g., conditions, discounts) rather than entering a negative price.
  If the negative price is due to a data entry error, correct it to a valid positive value.
  If the business scenario requires a zero price (e.g., free goods), enter zero instead of a negative value.
  Review any custom validations or user exits that might enforce this check.
