Leasing an asset to customer

Question

I'd like to have your input/recommendations in configuring the following scenario in SAP 4.6C:
We buy super-computers from our vendors on a 3 to 5 year lease. Each supercomputer is recorded as an individual Assets via Asset Master records. We pay our vendors based on usage time, i.e. number of days in that month * 24 hrs * 60 min minus any downtime on maintenance, upgrades, patches etc.
Often a few years down the lane we have little or no inhouse use for these assets and at that point we lease these supercomputers to our customers. Our Vendors invoice us based on Customer's usage and we in turn bill the customers with a 10 to 15% markup. 
Please guide me in mapping this scenario in SAP.
Thanks,
Raj A

You can handle the scenario with (Time & Material) Resource Related Billing, incase you want to change the customer based on time usage. This can be handled along with PS / CS & FI consultant.
Incase you intend to Bill the Customer for Fixed Value, you can go ahead with Periodic Billing. This can be configured using Periodic Billing.
1. Create New Sales Order Type, say ZOR (Copy of OR) through T.Code: VOV8
Maintain Delivery Type as LF & Billing Type As 'F1' - Order Related / 'F2' Delivery Related.
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Header > Define Sales Documents Types
2. Assign New Sales Document Type to Sales Area, For Eg:
1000 (S.Org) / 10 (D.Channel) / 10 (Division) / ZOR (S.O Type)
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Header > Assign Sales Area to Sales Document Type
3. Create New Item Category, say ZTAN - Copy of TAN (For delivery Related) / ZTAD - Copy of TAD (For Order realted) / ZTAS - copy of TAS (For Third Party)
Maintain as under (others remaining same)
Billing Relevance: I
Billing Plan Type: 02
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Item > Define Item Category
4. Assign Item Category, for ex (assuming Usage & higher level item category as blank):
Sales Document Type | Item Category Group | Default Item Category
ZOR | NORM | ZTAN
ZOR | DEIN | ZTAD
ZOR | BANS | ZTAS
IMG > Sales and Distribution > Sales > Sales Documents > Sales Document Item > Assign Item Category
Note: In the above Billing Type '02' plays the main controller for periodic billing. while execution of process some messages pop-up with respect to date, just press enter & skip them. In Sales order, at item level, we require to maintain the billing plan.
Follow the Sales cycle as normal sales cycle for particular Scenarios
