Configuration of configurable material
In a Window manufacturing: It is totally a customer specific(configurable) item and each customer will have its own requirement of different sizes of windows and doors for buildings.
For example, customer wants following :-
As soon as sales order created for configurable material he should be able to know the planned cost,availability of BOM items, resources etc.
In configurable products you need:
1.- Define as KMAT material.(嗯，一定要用KMAT的material type嗎？)
2.- Define classes and characteristics.
3.- Create a configurable profile and asign it to Kmat.
4.- You need a SuperBom and Super routing for this material.
5.- Define global and local dependencies to control this materials and operations.
When you enter to VA01 for a Sales requirement the characteristics will be displyed and you'll be able to configure the product.
If you have created KMAT, class, characteristics, dependency but is still not able to see the characteristics values for configuration in transacton VA01.
You are not getting any error message in sale order creation.  Even configurable tab is not appearing in the screen of sale order.   Make sure you have made a configurable profile (CU41) and assigned to KMAT? In this you link the classes and the characteristics with Kmat material. You have to check the class category is 300.
Which item category group did You put on the sales view on the material master and did that lead to an item cat. in the sales order which initiates the configuration ?
Is the "Configurable material" box checked on the material master?
 
Please check wheather you have assigned variant class 300 to the kmat (Configurable material) in the material master. I presume that you have selected classification view while creating material master for this KMAT.
Ensure that you have done the following for configurable material :-
Material master:
You have created material of material type "configurable material"(KMAT).
In basic data 2 check box for configurable material is selected.
Material is assigned to class type "300" in the classification view.
In sales org 2 view General item category group is "0002"(Configurable).
In MRP3 view strategy group "25" (Make to order for configurable material) is given in the field.
Classification:
You have created a class of class type 300.
Characteristics and its values are created and assigned to above class.
Configuration Profile:
Configuration profile for object type "material" is created for the material KMAT.
This profile is assigned to class type 300 and released.
Profile is assigned to class.
Please, check the requirement type on your sales order. It should be related to Configurable material as KEK (make-to-order configurable material), KEKT (order + comsumption of variant) or KEKS (order + consumption of charracteristics planning).
If you don´t use any or this, the system doesn´t display configuration table and the sales order seems normal.
You now be able to configure material in sale order on the basis of characteristic and values.
Now, how can you trigger BOM items and quantities in PP order from configured sale order.
After you save the sales order you can create a production order to a sales order in transaction CO08. Or, if you have several levels on your product you can run an MRP (if your material is planned using MRP type "PD" or other previsional MRP type) and convert the planned order. The system create an specific BOM and Routing for this sales order configuration. You can check this specific configuration in production order header -> configuration.
