• What is the cause and solution for SAP error message AJ279 - Do not use price type "scale price" for price category "flat rate" ?

  The SAP error message AJ279, which states "Do not use price type 'scale price' for price category 'flat rate'," typically occurs in the context of pricing conditions in SAP, particularly when dealing with pricing procedures in sales and distribution (SD) or materials management (MM).
  Cause:
  This error arises when there is a mismatch between the price type and the price category defined in the pricing condition records. Specifically, it indicates that the system has detected an attempt to use a "scale price" type in a context where a "flat rate" price category is expected. 
  
  Price Type: Refers to how the price is structured (e.g., scale pricing, flat rate).
  Price Category: Refers to the classification of the pricing condition (e.g., flat rate pricing).
  
  In this case, the system is enforcing a rule that does not allow the combination of these two incompatible pricing structures.
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Pricing Condition Records:
  
  Go to the transaction code VK11 (Create Condition) or VK12 (Change Condition) to review the pricing condition records.
  Ensure that the price type and price category are compatible. If you are using a flat rate, ensure that the price type is set accordingly (not as scale pricing).
  
  
  
  Adjust Pricing Procedure:
  
  Review the pricing procedure assigned to the sales document or purchase order. You can check this in the configuration settings (transaction code V/08 for sales or M/08 for purchasing).
  Ensure that the pricing procedure is correctly configured to handle the types of pricing you intend to use.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or help files for detailed information on pricing types and categories. This can provide insights into how to properly configure your pricing conditions.
  
  
  
  Testing:
  
  After making the necessary adjustments, test the changes by creating a new sales order or purchase order to see if the error persists.
  
  
  
  Consult with SAP Support:
  
  If the issue continues after checking the above points, consider reaching out to SAP support or your internal SAP team for further assistance.
