Plant Maintenance with MRP

Dear all,

Sorry because i can't find a forum for PM function, so i have to post this subject in PP forum. But I think thera are some solution for my problem.

1. Does anyone run MRP for Plant Maintenance??? because I have to make requirement planning of material for maintenance plan in my company.

2. I have a equipment BOM, so when I have a maintenance order. Why the system does not auto load all of component in BOM into tab component of maintenance order? If I want to load assign component fof maintenance order, I have to do this by choose each item in BOM equipment and assign it to maintenance order.

Thank all
