SCENARIO:
                 A new User Defined Field is created at the timesheet row level and a number is entered in it on the current timesheet period. Now, a future timesheet period is created and the 'copy from' feature is used on the future timesheet period. This will copy the data from the current timesheet period. However, after saving the timesheet period on which the copy from button was used with a few modifications, if there is another future timesheet generated and the 'copy from' feature is used, the system does not copy the data from the last saved timesheet period.

RESOLUTION:
                The data that will be copied to the timesheet on using the 'Copy From' button will be the data from the current timesheet period. This means that if the data is entered on the current timesheet period and saved and 'Copy From' feature is used for a future timesheet period, the data from the current timesheet period will be copied. If another future timesheet period is opened and the 'Copy From' feature is tried, it will not copy the data from the last saved timesheet, it will only copy the data from the current timesheet period.
