  SAP Error Message:
  WES_OUTBOUND321 Material &1 ignored, as sales unit &2 differs from discount unit &3
  
  Meaning / 
  Cause:
  This message occurs during outbound processing (e.g., in SD billing or pricing) when the system detects that the sales unit of the material differs from the discount unit defined for that material. Because the units do not match, the system ignores the material for discount or pricing conditions that depend on the discount unit.
  
  Material &1: The material number involved.
  Sales unit &2: The unit of measure used in the sales document.
  Discount unit &3: The unit of measure defined for discount calculation.
  
  In SAP, the discount unit is a unit of measure used specifically for pricing and discount calculations, which can be different from the sales unit. If these units differ, the system cannot correctly apply discounts or pricing conditions, so it ignores the material for those calculations.
