My client clubs together certain products with quantities in something they call Product Group.  The customer calls in and orders for the product group and automatically gets in all the associated materials.

Do we need a Sales Order BOM to handle this?
 

Yes, you have to Confugure the Sales BOM.  But the confugaration of Sales BOM depends upon certain conditions like:

If you want to create the product group and price it at header level or
If you want to assemble the products and depending upon the assemblies you want to price .

For eg.  if the customer asks for a certain combinationa of Material A, B and C respectively,
then you create a Material Master record Material D with item category group as LUMF.

While the Materials A, B and C are created with standared item category groups NORM only.

Then create a sales BOM using Tcode CS01 and enter the following details:

Material : Material D
Plant : Plant in which you created the material.
BOM Usage : 5 (Sales and Distribution)

then give the Materials A, B, and C and give their respective quantities.

Before you have to create pricing condition records for Materials A, B, and C.

Then configure the item categories ( T - code : VOV4).

When processing the sales order, just give the Material D and the system will pick up the corresponding assemblies for that material and populate in the order.

The item category for the header item will be TAP
and the item cateory for the items will be TAN,

In this cas the Material D is called as the higher level Item , and all the assemblies are called as the subitems.

Here the subitems are relevant for pricing and delivery where as the header item is not relevant for neither pricing nor delivery.  It just acts as a text item.
 

This type of configaration of BOM is known as pricing at item level.   This is used when you dont know what quantities of assemblies the customer is going to order and if the price of the assembly keeps varies.

There is another way of configaring BOM which is pricing at header level.
The difference is that the Material Master D has to be confugured using the item category group ERLA.

Creation of BOM is same.

But you need to maitain the pricing condition record for the header item.

The item categories in this case would be
Header item : TAQ
Sub item TAE;

Where the header item is relevant for pricing and delivery. and subitems are not relevant for neither the pricing nor the delivery.

Depending upon your requirement you configure accordingly,
