  SAP Error Message:
  WRF_ARTICLELIST041
  
  Text: Difference between days is 0 - the difference must be at least +1
  
  Cause:
  This error occurs when a date range is specified in a process (often related to article lists, planning, or scheduling) where the start date and end date are the same, or the difference between the two dates is zero. The system expects the difference between the two dates to be at least one day (i.e., the end date must be at least one day after the start date).
  In other words, the system requires a minimum interval of one day between the two dates to proceed with the operation.
  
  When does it typically occur?
  
  When creating or processing article lists or planning data where a validity period or date range is required.
  When entering date intervals for reports, planning, or master data maintenance.
  In scenarios where the system validates date ranges for consistency and logical correctness.
  
  
  Solution:
  
  Check the date inputs: Verify the start and end dates you have entered. Ensure that the end date is at least one day after the start date.
  Adjust the date range: Change the end date to be greater than the start date by at least one day.
  Validate date fields: If the dates are populated automatically or via a program, check the logic that sets these dates to ensure it does not assign identical dates.
  Review user input or interface: If the dates are entered manually, inform users about the requirement for a minimum one-day difference.
  
  
  Related Information:
