Once a key date has been met you can mark it as complete, allowing you to focus on outstanding and upcoming key dates.
How to mark as date as complete:
On your relevant product line, select the 'Details' option to open the detailed view menu on the right hand side of your screen.
Select the 'Procurement' tab at the top of your side menu view.
Check the Complete box next to each date to mark the date as complete. Completed dates will not show within your Procurement hub and will be displayed differently within your Schedule Procurement tab. You can easily unmark an item as complete by deselecting the Complete checkbox.
