Hi.
Days forewarning is not displayed in any other screens. This is a value that is used to control how many days prior to the due date a pending maintenance is created by the due calculation function.
An example:
You have an item in your maintenance plan with a 30 days interval. This item has 10 days forewarning.
The last time the item was performed was November 2nd. Next due will then be December 2nd.
A pending maintenance event will then be created when the due date runs on December 2 - 10 = November 22.
On the pending event itself, you will only see the due date. The main purpose is to avoid filling up your pending maintenance event list.
I hope that this helps.
