On the Landing Page we show links to the requests due to expire.

 

To specify when requests expire:

1. From the Module Menu select Maintenance, Requests and then General Parameters.
2. Set the Due to expire days.
3. Click Save & Close.

For example, if today's date is 10/3/18 and Due to expire days is 21 then requests that have a Last date required before 31/3/18 will appear as "Due" on the Landing Page.
