Hi,
Before you create a variant BOM, please note the following:
The material for which you want to create a variant of an existing BOM must not have a BOM.
The BOM of the material that you want to use to create a variant cannot be a multiple BOM.
The material whose BOM (variant BOM) you want to copy must have a BOM with the same usage as the one you selected for your new variant.
Does the BOM that you want to use to create a variant have a history requirement?
If so, which change number do you use? If you want to make the change with reference to an engineering change request (ECR), the ECR must first be converted to an engineering change order (ECO).
The base units of measure of the variant materials must be the same, because the BOMs base unit of measure must be the same as the base unit of measure in the material master record.
All the variants of one variant BOM form a BOM group. Within the BOM group, each item has a unique item ID. You can enter the same item ID for logically-related items, such as different versions of an item.
Steps to create variant bom:
1) From the bills of material menu, choose Material BOM ® Create.
You see the Create material BOM initial screen.
2) Enter the data for the variant BOM you want to create.
The material for which you want to create a variant of an existing BOM cannot have a BOM with the same usage in the selected plant.
u2013 In the Material field, enter the material for which you want to create a variant.
u2013 In the Plant field, enter the plant in which you want the variant to be valid.
The BOM that you want to use to create a variant must exist in this plant.
You can extend the area of validity of the BOM later on by using the Create plant allocation function.
u2013 Enter the Usage.
If a default parameter is defined for the Usage field in your user master, you see this value. Otherwise you see the usage that was last entered in this field.
When you select a usage, please note that the usage determines which item statuses you can set. This means that you can only maintain certain indicators (for example, relevant to production, relevant to costing) at item level.
The material that you want to use to create a new variant in the selected plant must already have a BOM with the usage that you enter here.
u2013 Do not make an entry in the Alternative field, for a variant BOM.
In a variant BOM, the alternative is not relevant to the user. The alternative is only required internally for storing the variant BOM. For this reason, if you do make an entry in the Alternative field, the system ignores your entry.
3) Enter the validity data for the variant BOM.

Maintaining the Create Material BOM Initial Screen
If you create the variant with reference to a change number, the entire BOM group (this includes all variants of the variant BOM) has a history requirement.
This means that you can only change or extend the BOM if you enter a valid change number.
4) If you want to check the data you enter, choose Check entries.
Do not confirm your entries by choosing ENTER, because this creates a simple BOM.
