Component as a configurable material KMAT?

Question

Hello Gurus,
to be more clear with my question, I try to explain it by an example: A characteristic value assignment is made while busy with a sales order creation (VA01) for a configurable material SHOWER CUBICLE (material type KMAT). One of the characteristic is a Width/Height of a walls, so a value assignment of this characteristic can be 900/2000 for instant. After MRP execution, a BOM is exploded and all materials are determined by a super BOM. Every think is working out perfectly if a component u201CWALLu201D is managed by a class type 200. This means that there are defined beforehand all the material masters for each possible variants of component "WALL". In consequence a purchase requisition is generated for a specific material, in this example for a u201CWALL900X2000u201D.
My question is: To avoid to define and maintain the material masters for the variants, is it possible that I would define a component WALL as a configurable material KMAT? My tests show that a MRP can generate a purchase requisition for the material WALL (though it is KMAT), but without a value assignment taking over from a sales order. Very probably this is not a configuration issue, but I suppose I should use a user-exit or other functions to configure a component automatically? Which one?
Many thanks already in advance

Jari ,
you can put a configurable material inside a configurable material BOM.
and while configuring the salable product in sales order , you can assign value to lower level  KMAT.
depend upon procurement type of component procurement proposal will be created.
for question about refletion of values from sales order to PO created, you need to check have you set up all master data and dependancies correctly.
as you mention you are using class 200 , what i guess is you are using classes inside BOM instead of materials and value assigned to calss is selecting appropiate material.
check and come again.
