Work Center Hierarchy

Greetings,

I am working in PM module, I want to learn about how worck center hierarchies process in PM. Customer wants to create one superorder work center and 4 suborder work center related to former. We want system to collect all capasities of suborder work centers for superorder. I don't have enough experience about it.

If I make superorder work center's capasity 0 deliberately, does SAP collects capasities of suborders or not?

If I assign maintenance order to superorder work center, does SAP assign process to suborder ones or not?

Thanks in advance,

Regards,

Xantrique.
