Equipment Hierarchy

Dear Experts,

I have a question about the equipment hierarchy, what the purpose of the equipment hierarchy.

it's only used for master data purpose only or there is another purpose.

I have tried a lot but I didn't find anything.

I have made a equipment hierarchy and then I have checked the cost report (MCI8) and I found that it only calculate the cost the superior equipment only not the whole hierarchy.

Kindly advise.

Thanks.
