Copying an Existing BOM
The differences between alternative BOMs for a material are usually only very small (for example, the component quantities are different). For this reason, you can copy an existing alternative.
How to copy an existing BOM:
You see the following warning message:
Alternative <number> added to BOM (multiple BOM)
Confirm this message. If the BOM for which you want to create an alternative has a history requirement, you see a message. In this case, you can only create an alternative if you enter a valid change number.
You see the Copy from dialog box.
The Alternative field is available for entry.
You have the following options:
Select an alternative from the alternative overview. Choose Copy from.
You see the item overview of the BOM you are copying from.

If there are no valid items 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>
If you confirm this warning message, you see the Quantities/long text header detail screen of the BOM that you are copying.
