  Solutions:
  
  Check Time Entries: Review the start and finish times for the operation in question. Ensure that the finish time is set to a time that is later than the start time.
  Adjust Scheduling: If the operation is part of a sequence, check the scheduling of preceding and succeeding operations to ensure that they are logically ordered.
  Use the Scheduling Functionality: Utilize SAP's scheduling tools to automatically calculate and adjust start and finish times based on the defined routing and available capacity.
  Review Time Zone Settings: If applicable, check the time zone settings in the user profile and system configuration to ensure they are consistent.
  Data Validation: If the error arose after a data migration, validate the data for any inconsistencies and correct them as necessary.
