Deadline Monitoring

Hi Gurus,

I just wanted to know why do we need to define a back ground job (SM36) and run a program RISTRA20 for batch.

If we scheuled all the maintenace plans thru IP30 or IP10...it`s automatally going to call the maintenace objects based on call horizon and will create a work order.

what is the need to defining job ? is tht require ? if yes what will the real live situation in plant.

It would be great if someone can help me on this thru the whole process.

regards,
