  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 or other master data with validity periods.
  When creating or changing info records or other master data with validity dates.
  
  
  Solution
  
  
  Check existing validity periods:
  
  Review the existing condition records or master data for the material and unit in question.
  Use transaction codes like VK13 (Display Condition Records) or MM03 (Display Material Master) to check validity periods.
  
  
  
  Adjust validity periods:
  
  Modify the new record's validity period so it does not overlap with existing periods.
  Alternatively, adjust the existing records' validity periods to avoid overlap.
  
  
  
  Delete or archive obsolete records:
  
  If old records are no longer needed, consider deleting or archiving them to clear the overlap.
  
  
  
  Use appropriate transaction codes:
  
  For pricing conditions, use VK11/VK12 to maintain condition records carefully.
  For material master data, use MM02 to adjust validity periods.
  
  
  
  Check for unit of measure consistency:
  
  Ensure that the unit of measure is consistent and correct for the material.
  
  
  
  
  Additional Information
  
  This is a warning message (W_), not an error, so the system allows you to save the record but warns you about the potential conflict.
  Overlapping validity periods can lead to incorrect pricing or master data usage during sales or procurement processes.
  It is a best practice to maintain clear, non-overlapping validity periods to avoid ambiguity.
  If overlapping periods are intentional (e.g., for different sales organizations or distribution channels), ensure that the key fields differentiating the records are correctly maintained.
