When creating a planning for your tender, you can set reminders for designated dates in the future. This way you receive notifications about upcoming events in your tender.
Go to 'Planning' and click on the icon behind the date you want to set a reminder for. In the popup window you can now set the reminder and indicate when you want to be notified.
As a Lead Buyer in a tender, you can also set reminders for your colleagues. To do so first, click the 'manage' link behind the the date you want to assign colleagues to, and add 'Responsible Persons'. For each responsible person, you can now set individual reminders by clicking on the same icon again, behind their name.
It is not possible to set reminders for vendors.
