Selecting a Variant BOM to Copy 
How to select a variant BOM to copy:
- If the data you entered on the initial screen is correct, choose Create variant of.
You see the Create variant of dialog box.
- In the Material field, enter the material whose BOM you want to use to create a variant.
- Confirm your entries.
The system makes a series of checks, for example:
- The system checks whether a BOM already exists for this material. The system determines the values for the plant and usage from the data you entered for the new variant on the initial screen.
- If no items are valid on the valid-from date you entered on the initial screen, you see the following warning message:
No items are valid on <valid-from date>
Confirm this message. You see the Quantities/long text header detail screen.
If your data is correct, you see the Copy from screen. This screen shows the items of the BOM you are copying.
