• The SAP error message:
  WTADDI446: Procedure for additionals &1 not defined for this sales order
  
  Meaning / 
  Cause:
  This error occurs during sales order processing when the system tries to determine the pricing procedure for additional costs (such as freight, surcharges, or other additional charges) but cannot find a defined pricing procedure for these additionals in the sales order.
  In SAP SD (Sales and Distribution), pricing procedures control how prices, discounts, surcharges, and additional costs are calculated. The system uses a pricing procedure determination logic based on various factors like sales area, document pricing procedure, customer pricing procedure, and condition types.
  When the system encounters additional costs (e.g., freight, packaging, or other surcharges) and tries to apply a pricing procedure for these additionals, it looks for a defined procedure in the sales order. If none is found, it throws this error.
  The placeholder &1 in the message will be replaced by the name of the missing
