SOLIDWORKS Composer 2020 // BOM

Hi all

I'm new to SOLIDWORKS Composer, my role is to generate assembly instructions and production bills of materials.

I have several questions:

1. Is it possible to get a BOM with hierarchical view (with the "save BOM tree" function in the left Workshop/BOM panel)

It will be important for me to know the names of all the parents for my articles (level 1,2,3,...)

I don't see how to add this data to the BOM table?

The only solution I found was to set the Tooltip property to a parent level and add the Tooltip in my BOM. But that only gives me one level.

2. How to exclude parts / include groups effectively in the BOM?

By clearing the BOM ID property for the elements that we want to make disappear, and defining a value for the elements that we want to integrate into the BOM.

This BOM ID property seems very fragile to me: because it resets too easily in case of clumsiness (reset BOM ID button), and I guess that this property resets as soon as you update the product (update)

Thanks in advance if any tips to share about BOMs on Composer.

Kind regards
