This error typically arises in the context of utility billing and meter reading processes.
  Cause:
  
  Data Entry Error: The most common cause is a manual data entry error where the current meter reading was incorrectly entered as being lower than the previous reading.
  Meter Malfunction: There may be an issue with the physical meter itself, such as malfunctioning or incorrect calibration, leading to inaccurate readings.

  System Issues: There could be a problem with the system configuration or data integrity issues within the database.
  
  Solution:
  
  Verify Readings: Check the current and previous meter readings for accuracy. Ensure that the current reading is indeed higher than the previous reading.
  Correct Data Entry: If the current reading was entered incorrectly, correct it in the system to reflect the accurate value.
  Inspect the Meter: If there is suspicion of a malfunction, inspect the physical meter for any issues and consider recalibrating or replacing it if necessary.

  Training: Providing training for staff involved in meter reading and data entry can help reduce the occurrence of such errors in the future.
