Client receives funding from government, which has strict rules.
One of the rules is that no expenses should be posted outside the duration of the WBS (funding period).
client creates a WBS with the start and end date: 1 Jan 2009 to 31 May 2009.
If a posting is done outside that period, then it will not be funded by the government.
However, users post in March 2009 with posting date 15 June 2009.
The government will not fund those expenses.
