  SAP Error Message:
  WRF_ARTICLELIST042
  
  Text: Difference between days is less than 0 - difference must be at least +1
  
  Cause:
  This error typically occurs in SAP Retail or related modules when a date range or period is being validated, and the system detects that the difference between two date values (usually an end date and a start date) is less than zero or zero. In other words, the end date is either before or the same as the start date, but the business logic requires the end date to be at least one day after the start date.
  Common scenarios include:
  
  Defining validity periods for articles, promotions, or price lists where the end date must be strictly after the start date.
  Setting up planning or forecasting periods where the duration must be positive.
  Uploading or maintaining article master data or related lists where date intervals are validated.
  
  
  Solution:
  
  
  Check the Date Fields:
  
  Verify the start date and end date values entered.
  Ensure that the end date is at least one day greater than the start date.
  
  
  
  Correct the Date Range:
  
  Adjust the end date to be after the start date by at least one day.
  If the dates are coming from an interface or upload, correct the source data accordingly.
  
  
  
  Review the Business Logic:
  
  Confirm that the requirement for the date difference being at least +1 day is valid for your business process.
  If the logic needs to be changed (e.g., allowing same-day start and end), this would require a customization or enhancement, but usually, the system enforces this to avoid invalid periods.
  
  
  
  Reprocess the Transaction:
  
  After correcting the dates, retry the transaction or data upload.
  
  
  
  
  Related Information:
  
  This message is part of validation checks in SAP Retail or related modules where date intervals are critical.
  The message ID prefix WRF_ suggests it is related to SAP Retail Forecasting or Article List processing.
  Similar errors can occur in other SAP modules when date intervals are validated (e.g., promotions, contracts, planning).
  Always ensure date formats and time zones are consistent to avoid unintended date differences.
  If the error occurs during a batch upload or interface, check the data file for incorrect date entries.
