  Error Message
  W_CB449: Overlapping validity period for material &1 unit &2
  
  &1 = Material number
  &2 = Unit of measure
  
  
  Cause
  This warning message occurs when you try to create or maintain a condition record (e.g., pricing, discounts, surcharges) or master data that has validity periods overlapping with existing records for the same material and unit of measure.
  In SAP, condition records or master data entries often have validity periods defined by a start and end date. The system expects these periods not to overlap for the same key combination (material + unit). Overlapping periods can cause ambiguity in determining which condition or data record applies at a given time.
  
  When does it occur?
  
  When maintaining condition records in pricing (transaction codes like VK11, VK12, VK13).
  When maintaining material master data or related data with validity periods.
  When maintaining batch master data
