How to set budgeted earn value unit cut off

Hi,

i have a difficulty on how to get budgeted labor unit as per my cut off time. Previously i always use 'Update Progress' and then i put there date and my cut off time. Example, 2-Sept @ 1600hrs. Then i open column for 'Earn Value Labor Unit'. Expand all, then copy to excel. After that keep repeating the same process for my data for that day at 2000hrs cut off time. Its mean 2 times per day for the 30 -60 days project. This is what i use before in p3. Maybe got any other idea....

need help, tq
