I keep getting this when I or another colleague tries to complete a timesheet on Online
We can't display the selected time period. It might be closed or your administrator hasn't created it yet. Please try a different date.
What is the issue?
When you click on timesheet in the left navigation, Project Online creates the timesheet for the current timeperiod. Could you please check if timesheet period is available. Below are the steps.
Check if the timesheet period is available for current timeperiod.
