Hi Komi,
Thanks for your advices. It meets my requirement. When I set up the parameter show as 'version' just like below. I can observe the BOMs are connected by which items and the BOM construct details.

For example, From the below lines, I can know the BOM 000175 of the item D0003 contains one item MT001.
My concern is the relationship between the BOM 000175 and the item D0003 and other items which use the BOM 000175.

Thank you
