• What is the cause and solution for SAP error message NAA399 - The price determination date is not in the validity period (PO) ?

  The SAP error message NAA399, which states "The price determination date is not in the validity period (PO)," typically occurs in the context of purchasing documents, such as purchase orders (POs). This error indicates that the date on which the system is trying to determine the price for a material or service does not fall within the validity period of the price conditions defined in the system.
  Cause:
  
  Price Validity Period: The price conditions (e.g., pricing agreements, contracts) have a defined validity period. If the date of the purchase order or the date of price determination falls outside this period, the error will occur.
  Incorrect Date: The date on the purchase order may be incorrectly set, or the system may be using a date that is not intended for price determination.
  Missing or Incorrect Conditions: The pricing conditions may not be set up correctly in the system, or there may be missing entries for the relevant material or vendor.
  
  Solution:
  
  
  Check Validity Period: Review the validity period of the pricing conditions associated with the material and vendor in the system. Ensure that the date of the purchase order falls within this period.
  
  You can check this in the condition records (transaction code: MEK1 for creating, MEK2 for changing, MEK3 for displaying).
  
  
  
  Adjust Purchase Order Date: If the purchase order date is incorrect, adjust it to a date that falls within the validity period of the pricing conditions.
  
  
  Update Pricing Conditions: If the pricing conditions need to be updated (e.g., if they have expired), create new condition records with the correct validity dates.
  
  Use transaction codes like MEK1 to create new conditions or MEK2 to modify existing ones.
  
  
  
  Check for Multiple Conditions: If there are multiple pricing conditions for the same material and vendor, ensure that the correct one is being applied based on the date.
  
  
  Consult with Procurement Team: If you are unsure about the pricing conditions or how to adjust them, consult with your procurement or purchasing team for assistance.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as MEK1, MEK2, MEK3, ME21N (Create Purchase Order), ME22N (Change Purchase Order), and ME23N (Display Purchase Order).
  Price Determination: Understand how SAP determines prices based on conditions, including the sequence of condition types and their priorities.
  Documentation: Review SAP documentation or help files related to pricing conditions and purchase order processing for more detailed guidance.
