  Error Message
  W_CB431: Overlapping validity period for material &1
  
  Cause
  This warning occurs when you try to create or change a master data record (such as a material master, condition record, or any other object with validity periods) and the validity period you are entering overlaps with an existing validity period for the same material (or object).
  In SAP, many master data records and condition records are maintained with validity periods to specify when they are effective. Overlapping validity periods can cause inconsistencies or ambiguities in data processing, so SAP issues this warning to alert you.
  
  Typical Scenarios
  
  Creating or changing a material master record with multiple validity periods for certain views (e.g., sales, purchasing).
  Maintaining condition records for pricing or discounts where validity dates overlap.
  Entering data in tables or transactions that require non-overlapping date ranges for the same material or key.
  
  
  Solution
  
  
  Check Existing Validity Periods:
  
  Review the existing validity periods for the material or object in question.
  Use transaction codes like MM03 (Display Material Master) or the relevant transaction for the object to check current validity dates.
  
  
  
  Adjust Validity Dates:
  
  Modify the new validity period so that it does not overlap with any existing periods.
  If you need to extend or change the validity period, adjust the existing records accordingly to avoid overlaps.
  
  
  
  Delete or Archive Old Records:
  
  If old records are no longer needed, consider deleting or archiving them to clear the way for new validity periods.
  
  
  
  Use Correct Date Ranges:
  
  Ensure that the start date of the new validity period is after the end date of the previous period or vice versa.
  
  
  
  Consult Documentation or SAP Notes:
  
  Sometimes, specific modules or customizations may have particular rules about validity periods. Check SAP Notes or module-specific documentation if the problem persists.
