Unique PM Schedule setup requirement, need help please.

Hello Gurus,

As of now in our organization we have PM services for our Assets setup like this:

PM1 - 250

PM2 - 500

PM1 - 750

PM3 - 1000

PM1 - 1250

PM2 - 1500

PM1 - 1750

PM4 - 2000

In the case above the interval as you can see in 250 hours. The PM2 suppresses PM1, PM3 suppresses PM2 and PM4 suppresses PM3.

Sometimes we also use 300 hour intervals instead of 250.

Anyway, the requirement I have is that one of our users has requested for an inspection WO to be forecasted 100 Hours before every PM service. This allows them some time before a PM is due to do a quick inspection and procure any material they might require and complete the job along with the PM and cut down on down time.
