How to use BOM Items on Sales Order?

Dear All Experts,

I need to configure BOM items to show them on Sales Order like mentioned below:

Item (Room Set)

and its Components like:

1) Air Condition

2) Bed Set

Here we are using Purchasing, Inventory & Order Management Module, just to show the information of BOM Items, nothing to do more with them.

Please help us to setups which nature of Items and how we can use them.

Thanks in Advance..
