Special pricing requirement in BOM

Question

Dear Gurus,
Our Client is assembling Machines with sub assemblies and so on.  Now when ever a customer comes he asks for a different combination, so we have designed the MMR as ERLA and has a price at header level and once assembled will be PGIed at header level. OK till here.
Now the issue is, client wants to have a facility in the system where, when ever a client comes for an order, marketing ppl should put all the different sub items in the quotation and the system should pull out the prices of those and others that are specified and marketing ppl should be able to give a Quotation. We need the pricing to be done at Sub Item level and delivery will be done at header level.
Main Item = ERLA = "THUNDER D82" = 5000.00
Sub Item 01 = TAE = Motor 10 HP = 2000.00
Sub Item 02 = TAE = Gear Box 4 Teeth = 1750.00
Sub Item 01 = TAE = Compressor 5 TON = 1250.00
Now when a new customer comes in, we need a facility where in VA21, THUNDER D82 is entered and at sub item level the requirement is:
Sub Item 01 = TAE = Motor 12 HP = 2750.00
Sub Item 02 = TAE = Gear Box 5 Teeth = 2100.00
Sub Item 01 = TAE = Compressor 7.5 TON = 1750.00
Main Item = THUNDER D82 = 6600.00
We cannot maintain a new MMR since every customer can demand a new combination. Kindly remember, once assembled this machine is to be priced at header level and delivered / PGIed at header level. And since the machine will have a lot of other parts, we cannot use LUMF at MMR level.
So how to achieve this? Help me out here Gurus. . . . . .

Hello Venkat
You need to use a combination of Variant Config (VC) and BOM to make this work.
1) Set up Main Item (THUNDER D82) as configurable material . Set up characteristics (CT04) for the options (example Gear Box would be one characteristic with its values as 4 teeth,  5 teeth etc. These are the values user would choose in the sales order in the configuration tab. Set up a class of variant class Type (300,  include all these chars in that and finally link this to the material via config profile.
2) Set up a master BOM with all the components possible and use selection conditions to choose them based on configuration in the order.
3) Introduce Variant Pricing conditions (VA00) to add price for the component selected in the main item's pricing. This also involves using Variant table and/or Dependencies.
This is too brief and very broad based. It involves many steps but will work if you go at it methodically.
Let me know if you get any specific doubts as you go through the steps. Take care.
