The BBS only allows 40 hours to be claimed each week. TrackYourHours will alert you when you have logged more than 40 hours in a week. However, the software does NOT subtract the excess hours from your valid total because there is no way for the software to determine exactly which hours should be excluded (that decision is up to you). When you receive this alert you should review the week in question with your supervisor.
Example of this alert:
Week of October 28, 2012: No more than 40 recorded hours permitted in a week.
Hours have not been subtracted from your valid total. When your hours are reviewed the hours above 40 will not count. You should review this week to determine how many hours will not be counted.
