Hi,

If you are looking to get a import template for bom with components, you can easily prepare the template by yourself.

Follow the below steps:

1. Create a BOM with one or two components

2. Go to the tree view, select the created BOM and export it with necessary fields.

3. Now you will get excel/csv file as per the choosed option

4. You can modify the file and use it as template for further import.
